Answer:
21 and 35
Step-by-step explanation:
21 for the first box, when it is in parenthesis you multiply each, so then 35 for the second box
7 times 3 then 7 times 5
The two numbers are 12 and 5.
Two equations can be derived from this question
5x + 2y = 70 equation 1
4x - 2y = 38 equation 2
Where:
x = larger number
y = smaller number
In order to determine the larger number, the following steps hare to be taken:
Add equation 2 and 1
9x = 108
Divide both sides by 9
x = 108/9
x = 12
In order to determine the smaller number, substitute for x in equation 1
5(12) + 2y = 70
60 + 2y = 70
70 - 60 = 2y
10 = 2y
y = 5

Answer:
<h2>$9.48</h2>
Step-by-step explanation:
The total amount for the order is
$9.75+$29.99+ $15.00=$54.74
let the money her mother owes her be x
so summing all the amount plus the balance given to her must equal $54.74
so x+40+5.26=54.74
solving fo x we have
x+45.26=54.74
make x subject of formula we habe
x=54.74-45.26
x=9.48
Nicoles mother owe Her $9.48for babysitting
This can be seen as a ratio of 2 numbers. It it says that 2/9 is the ratio of catchOfDay/totalLunches.
So:
2/9 = catchOfDay/totalLunches
It also says that the catchOfDay was ordered 24 times and we want to find totalLunches, represented by x.
So:
24/x = catchOfDay/totalLunches
Putting the 2 equations together we can conclude:
2/9 = catchOfDay/totalLunches = 24/x
simplifying would give a final answer of:
2/9 = 24/x
If we wanted to solve for x, we cross multiply to try and isolate the x and get:
2x = 24 * 9
divide both sides by 2:
x = 24 * 9 / 2
Working this out then we get:
x = 108
Do you mean to ask what type of triangle that is? if so it would be a right triangle.
