One number is two less than a second number. Five times the first is 8 more than 2 times the second. Find the numbers
what is the value of the first and second number?
Answer:
PLEASE MARK BRAINLIEST
Step-by-step explanation:
a+2= b
5a - 8 =2b
a= b- 2
since(a= b- 2)
5(b-2) -8 = 2b
5b -10 - 8 = 2b
3b -18 =0
3b=18;b=6
since b =6
a= 6-2 ; a= 4

Step-by-step explanation:
40+ 46x + 2 = 180 degrees
46x = 180 - 42
x = 3
Answer:
46x+2°+40°=180° (adj angles on a str line)
46x+42°=180°
46x=180°-42°
=138°
x=138÷46

Q3). 0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.
[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]
The values of :
[tex]x = 2[/tex][tex]y = 3[/tex]The given equations are :
[tex]0.4x + 0.3y = 1.7[/tex][tex]0.7x - 0.2y = 0.8[/tex]now, let's multiply both the equations with 10 on both sides.
so, now our equations will be :
[tex]4x + 3y = 17[/tex][tex]7x - 2y = 8[/tex]from Equation second :
[tex]7x - 2y = 8[/tex][tex]2y = 7x - 8[/tex][tex]y = \dfrac{7x - 8}{2} [/tex]now, let's substitute the value of y from here into Equation first.
[tex]4x + 3y = 17[/tex][tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex][tex]4x + \dfrac{21x - 24}{2} = 17[/tex][tex] \dfrac{8x + 21x - 24}{2} = 17[/tex][tex] \dfrac{ 29x - 24 }{2} = 17[/tex][tex]29x - 24 = 34[/tex][tex]29x = 34 + 24[/tex][tex]29x = 58[/tex][tex]x = \dfrac{58}{29} [/tex][tex]x = 2[/tex]here, we got the value of x = 2, let's plug it in equation second to find value of y :
[tex]7x - 2y = 8[/tex][tex]7(2) - 2y = 8[/tex][tex]14 - 2y = 8[/tex][tex]2y = 14 - 8[/tex][tex]2y = 6[/tex][tex]y = \dfrac{6}{2} [/tex][tex]y = 3[/tex]And value of y = 3

Answer:
25 and 55
Step-by-step explanation:
Let's call the larger number L and the smaller S
L = 5 + 2×S
And the sum is:
L + S = 80 Subtract S in both sides:
L = 80 - S
Now, substitute this value of L in the first equation:
80 - S = 5 + 2×S Add S in both sides:
80 = 5 + 2×S + S
80 = 5 + 3S Subtract 5 in both sides
75 = 3S Divide both sides by 3
25 = S
We find the value of S, and now we substitute it in the second equation to find the value of L:
L = 80 - 25
L = 55

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. Let m represent the number of magazines and b represent the number of books. Which equation models the situation?
Answer:
3.95m + 8.95b = 47.65
Step-by-step explanation:
Since Hugh paid $3.95 for every magazine, m would be multiplied by 3.95
Since he also paid $8.95 for every book, b would be multiplied by 8.95
All of this will eventually add up to a sum of 47.65

4 ft
5ft
4 ft
9ft
8 ft
Answer:
52 square feet.
Step-by-step explanation:
length*width=area
Top rectangle = 4ft*5ft = 20sq.ft
Bottom rectangle = 4ft*8ft = 32sq. ft
20+32=52 sq.ft OR (4*5)+(4*8)=52sq.ft
Which is the area between the x-axis and y=x from x=1 to x=6
Answer:
