Answer:
the area of the striped rectangle= length ×breadth
Total units would be: 4+7 = 11
value of 1 unit = 44/11 = 4
Ratio would be: 4(4) & 7(4) = 16 & 28
Alexis and 3 friends buy:
-Pretzel $4.
-Sauce $1
-Drink $2
First we would multiply all the food prices by 4, since there is 4 people in total.
4 x 4 = $16
1 x 4 = $4
2 x 4 = $8
Now we're adding all the prices together.
16 + 4 + 8 = $28
At this point, we're going to make the expression, using all the steps that we did.
( 4 x 4 ) + ( 1 x 4 ) + ( 2 x 4 )
We used parenthesis to show that those expressions need to be done first before anything else.
This is how we make an expression and we find the total answer.
The expression would be: ( 4 x 4 ) + ( 1 x 4 ) + ( 2 x 4 )
The total cost would be: $28
Hope this helps!~

10
Step-by-step explanation:
4 * 2.5 = 10
Answer:
G = 78°
H = 98°
Step-by-step explanation:
Opposite angles in a cylic quadrilateral are supplementary. Therefore:
G + E = 180°
Substitute
8x + 1 + 11x + 8 = 180°
Add like terms
19x + 9 = 180°
19x + 9 - 9 = 180° - 9
19x = 171
19x/19 = 171/19
x = 9
G = 8x + 1
Plug in the value
G = 8(9) + 1 = 73°
H + F = 180° (opposite angles of a cyclic quadrilateral is equal?
Plug in the values
6y - 4 + 5y - 3 = 180°
Add like terms
11y - 7 = 180
11y = 180 + 7
11y = 187
y = 187/11
y = 17
H = 6y - 4
Plug in the value of y
H = 6(17) - 4
H = 98°
