Tomas and Tasha were hiking at a speed of 3.5 mph on their way back they were tired and their speed was 2 mph how long was the route if the way back took them 1 hour and 30 minutes longer (in miles)
Answer: 7 miles
Step-by-step explanation:
To get the length of the route use the expression for speed,
Distance = Speed × Time
Length of the route is 7 miles.
It's given in the question,
Speed of Tomas and Tasha initially = 3.5 mph
Therefore, distance travelled by both with the speed of 2 mph one way will be,
Distance = 3.5t [Here, t = time ]
Speed of both while coming back = 2 mph
And the time taken = t + (1 hour 30 minutes)
= (t + 1.5) hours
Therefore, distance travelled while coming back = Speed × Time
= 2(t + 1.5)
Since, length of the route is same both ways,
3.5t = 2(t + 1.5)
3.5t = 2t + 3
3.5t - 2t = 3
1.5t = 3
t = 2 hours
Now substitute the value of t in the expression to get the distance of the route,
Distance = 3.5t
= 3.5 × 2
= 7 miles
Therefore, route was 7 miles long.

which graph shows a non proportional relationship between x and y
Hi can u plz help me
Answer:
7 / 6
Step-by-step explanation:
( 2x + 6 ) / 5 = 4x - 3
2x + 6 = 5 ( 4x - 3 )
2x + 6 = 20x - 15
20x - 15 = 2x + 6
20x - 2x = 6 + 15
18x = 21
x = 21 / 18
21 = 7 * 3
18 = 6 * 3
x = 21 / 18
= ( 7 * 3 ) / ( 6 * 3 )
x = 7 / 6
Hence proved.

Consider the two linear expressions.
−(−12−6x−3) and 3.5−6x
Are the two linear expressions equivalent?
Drag a word or phrase to the box to correctly complete the statement.
The expressions are Response area.
The option "not equivalent" (2 of 2) has been grabbed. Press tab to choose where to drop it. Drop it by pressing the spacebar key. Cancel the operation by pressing escape.
Is it equivalent or is it not equivalent pick one
Answer:
Step-by-step explanation:
−(−12−6x−3)
= 12 + 6x + 3
= 6x + 15.
So 3.5 − 6x is not equivalent to −(−12−6x−3)
Both linear equations are not equivalent to each other and this can be determined by evaluating the equation (-(-12 - 6x - 3)) by using the arithmetic operations.
Given :
Equations --- -(-12 - 6x - 3) and (3.5 - 6x)
The following steps can be used in order to determine the given equations are equivalent or not:
Step 1 - Write the given equations.
=−(−12−6x−3) ---- (1)
= (3.5 − 6x) ---- (2)
Step 2 - Multiply -1 by (−12−6x−3) in the equation (1).
= 12 + 6x + 3
Step 3 - Add 12 and 3 in the above expression.
= 6x + 15 ---- (3)
Step 4 - Now, compare equation (2) and equation (3).
6x + 15 [tex]\neq[/tex] 3.5 - 6x
So, from the above steps, it can be concluded that both linear equations are not equivalent to each other.

state the gradient and the y-axis intercept of
y=3x+7
Step-by-step explanation:
the slope (or gradient) of a line is the factor of x.
in our case here : 3
it is expressed as ratio y/x and represents the amount of units y changes (and via the sign in what direction), when x changes a certain amount of units (again, via the sign in what direction). like when going from a point 1 to a point 2.
so, here we have 3 = 3/1, and that means, when x changes by 1 unit to the right (positive), y changes 3 units up (positive).
the y-axis intercept is simply the point, where x = 0. clearly, any point with the x coordinate being unequal to 0 cannot be on the y axis.
so, here
y = 3×0 + 7 = 7
=>
the y-axis intercept point is (0, 7).
What is 1/10=4/5y ?????
Answer:
y = 1/8
Step-by-step explanation:
Divide both sides by 4/5, 1/10 divided by 4/5; 4/5y divided by 4/5. In 4/5y divided by 4/5, the two 4/5s cancels out, leaving y alone. 1/10 divided by 4/5 equals to 1/8. Now you have, 1/8 = y, which is the same thing as y = 1/8. Therefore, the value of y is 1/8.
Answer: 1/8
Step-by-step explanation:
4/5y=1/10
*multiply both sides by 5, and you'll get
4y=1/2
*divide both sides by 4
y=1/8

The midpoint of an is m (-6,1). If the coordinates of a are (-5,7), what are the coordinates of b
Answer:
B= (-7, -5)
Step-by-step explanation:
The midpoint point formula is (X1 plus X2) divided by 2 to get the x value of the midpoint and do the same for the Y value, ( Y1 plus Y2) divided by 2. So, because you already have the midpoint you have to work backwards. So for the x value of B the formula would be (-5 + X) divided by 2 equals -6 and then you just solve for X. Same thing for the Y value (7 + Y) divided by 2 equals 1. Then you should get both values for B (-7, -5)

Figure B is a scaled copy of Figure A
What is the scale factor from Figure A to Figure B?
Answer:
[tex]1/2[/tex]
Step-by-step explanation:
Because they are scaled copies, the ratios of the sides are equal.
Figure A has a base of 6 units by inspection.
Figure B has a base 3 units by inspection.
So, the scale factor from Figure A to Figure B is [tex]3/6=\boxed{1/2}[/tex] and we're done!
The scale factor from Figure A to Figure B is 1/2
What is the scale factor from Figure A to Figure B?Figure A:
Base = 6 units
Height = 4 units
Figure B:
Base = 3 units
Heights = 2 units
Using Base of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 3 units / 6 units
= 1/2
Using Height of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 2 units / 4 units
= 1/2
Hence, 1/2 is the scale factor from Figure A to Figure B.

sarah has 214 bag of beads each bag has enough beads for 22 bracelets she estimates that since 200x 20 =4,000 there are enough beads for aT LEAST 4000 bracelets tell how how you can critique sarahs reasoning
Answer:
Sarah's reasoning sounds good to start. She rounded the available bags and their content, so the result, 4000 bracelets, should be really easy to reach.
The exact numbers are 214 bags * 22 bracelets / bag = 4708 bracelets; so as you see, Sarah took care of having room to loose some beads and yet the beads will be enough to make 4000 bracelets.
Of course, if you want to be sure, you should ask Sarah some questions. For example:
1) What proportion of beads are normally deffective?
2) What proportion of beads are normally lost when crafting?
So, if Sarah did not take into account those proportions she migth be overestimating the number of bracelets they can make.
Sarah's assumptions of having enough beads for at least 4000 bracelets is correct.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sarah who has 214 bag of beads each bag has enough beads for 22 bracelets
According to Sarah, there are enough beads for at least 4000 bracelets.
Mathematically -
x[e] ≥ 4000
Actual number of beads she could make = 22 x 214 = 4708 = x[a]
Since, x[a] > x[e], we can say that Sarah's assumptions are correct.
Therefore, we can say that Sarah's assumptions are correct.
