You will need to know how much each lunch cost
so
9.40 ÷ 4 = 2.35
so each lunch cost 2.35 dollars

now we need to find out how much it will cost for 10 lunches

10 x 2.35 = 23.5

so for 10 lunches it will cost 23.5

We have an equation: 4/10= 9.40/?

Cross multiply:
4*? = 9.40*10
⇒ ?= 9.40*10/4= 23.5

10 students would spend $23.50 on the same school lunch~

An object is translated by ( x + 4, y - 2). If one point in the image has the coordinates (5, -3), what would be the coordinates

Nikolay [14]

To find the pre-image we work backwards. Since the coordinates one of the translated image is (5,-3) and this image was translated with the formula (x+4, y-2), then we can just work backwords.
(x-4, y+2) --> (5-4,-3+2) -->(1,-1)
The correct answer is (1,-1)

A. find the value of a. B. Find the value of the marked angles.

Marat540 [252]

The marked angles are opposite angles, and as such they have the same measure. So, we have

$6a+11 = 2a+83$

Subtract 2a and 11 from both sides to get

$4a = 72$

Divide both sides by 4 to get

$a = \dfrac{72}{4} = 18$

Now that we know the value of a, we can compute the measure of the angles. We can also verify that the solution we found is correct by verifying that both expressions actually give the same result:

$6a+11 = 6\cdot 18 + 11 = 119$

$2a+83 = 2\cdot 18 + 83 = 119$
