Answer 1

Answer:

x=-5

Step-by-step explanation:

-5*-3=15

15-2=13

Hope it helps

Answer 2

Answer:

x = -5

Step-by-step explanation:

-3x-2=13

Add 2 to both sides of the equation

-3x-2+2=13+2

Simplify

-3x=15

Divide both sides of the equation by the same term

[tex]\frac{-3x}{3} =\frac{15}{-3}[/tex]

Simplify

x = -5

The required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.


Given that,
At a bargain store beast boy bought 5 items that each cost the same amount. Cyborg bought 8 items that each cost the same amount, but each was $1.50 less than the items beast boy bought. Both beast boy and Cyborg paid the same amount of money.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Let the cost of the item bought by the beast boy is x, and the item bought by the Cyborg be y,
According to the question,
5x = 8y
x = 8/5y  - - - - - - -(1)
y = x - 1.50  - - - - - -(2)
Substitute the value of equation 1 to equation 2
y = 8/5y - 1.50
5y = 8y - 7.50
7.50 = 3y
y = 2.5
Now, put y in equation 1
x = 8 / 5 × 2.5
x = 8 × 0.5
x = 4
Now, the costs,
5x = 4 × 5 = $20
8y = 8 × 2.5 = $20

Thus, the required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.

What is the relative error in the estimate?

Round to 2 decimal places.

Answers

Answer:

35.85%

Step-by-step explanation:

first, find the difference between the real value and the estimated value:

365.99 - 234.78 = 131.21

now divide the difference by the real value:

131.21 / 365.99 = 0.358507

is (6,-7) a solution to y+3=1/2(x+2)

My answers are not 100% Valid but here is my answer and response;
Answer: (4,-2)
To get x substitute 0 for y since you’re trying to find x, 0+3=1/2(x+2) add 0 with 3 to get 3 so 3=1/2(x+2) then use distributive property with 1/2 (x•1/2 = x/2) (2•1/2 = 1) so then the equation would look like this 3=x/2+1 subtract one from both side and get 2=x/2 then multiply everything by 2 to get x=4

are the two triangles congruent 6cm 13cm

Answers

Congruent triangles are triangles that have equal corresponding angles and sides.

There is no enough information to determine if the triangles are congruent.

From the images of the triangles (see attachment), we can see that the two triangles have 6cm and 13cm as the lengths of their sides.

However, the side lengths of both triangles are not corresponding, and the angle measures are not given.

Hence, there is no enough information to determine if the triangles are congruent.

320 - 275 = 45

2) None of the classes:

Answers

Answer:

m - 19 = 58

Step-by-step explanation:

Knowing that the word "difference" relates to subtraction, you should know that the equation involves a minus sign.

The problem also tells us that 58 is the difference. Basically, the word difference means the answer to a subtraction problem. So 58 is the answer to this equation.

However, we are not done yet. It says to use "m" to represent Matt's age. Thus, we can write our equation as:

m - 19 = 58.

The variable "m" goes first instead of 19 because the answer would no longer be 58. For instance, let's say m is 18, 19-18 is equal to 1...not 58.

Therefore, the correct equation is:

m - 19 = 58
