8*4=32
4*4/2=8
8-3-2=3
3*4/2=6
32+8+6=46
Answer:
$15.75 change
Step-by-step explanation:
Avery starts with $20.
She buys 2 tacos and 1 soda.
$1.25 + $1.25 + $1.75
= $4.25
$20 that she started with - $4.25 that she used.
$20 - $4.25 = $15.75
Answer:
1 / 16
Step-by-step explanation:
Divide each term by 2.
2 / 2 = 1
32 / 2 = 16.
1 / 16 = 2 / 32
Answer:
Perimeter: 16x + 16
Area: 40x + 15
Step-by-step explanation:
Remember, the perimeter is the sum of all the sides of a figure, it can be found by adding up all the sides. The area is the space within the figure, in the case of a quadrilateral can be found by multiplying the length by the width. Finally, in a rectangle, the opposite sides are congruent, parallel, and intersect in 90degree (right) angles.
Using this,
1. Find the perimeter
Since opposite sides are congruent, there will be two sides with a measure of ( 8x + 3 ), and two sides with the measure of 5. Hence the sum of all the sides would be
8x + 3 + 8x + 3 + 5 + 5
Add them together,
16x + 16.
The perimeter of the figure is 16x + 16
2. Find the area,
To find the area of a rectangle, multiply the length by the width.;
( 8x + 3 ) * 5
Distribute:
40x + 15
The area of the figure is 40x + 15
Answer:
7 is the value of x.
Step-by-step explanation:
Now we have to,
find the required value of x.
→ -18x - 19 = -145
→ -18x = -145 + 19
→ -18x = -126
→ x = -126/-18
→ [ x = 7 ]
Hence, the value of x is 7.
