After this step:
1. 8+x=7 multiply both sides by -1
2. x=-7-8 move the constants to the right
3.x=-7-8 Calculate
4. x=-15
Answer:
-663
Step-by-step explanation:
The first term is -14. The common difference is -11. So:
a = -14 + (-11) (n − 1)
When n = 60:
a = -14 + (-11) (60 − 1)
a = -663
10+3.75h=21.25
Subtract 10 from both sides 3.75h=11.25
Divide each side by 3.75, h=3. Kim rented the kayak for three hours.
Answer:
50 in²
Step-by-step explanation:
What is the area in square inches of the trapezoid below.
Area of a trapezoid = 1/2(b1 + b2) h
Where
b1 = First base = 8in
b2 = Second base = 12in
h = Height = 5in
Area of trapezoid = 1/2(8 + 12) × 5
= 1/2 × 20 × 5
= 50 in²
The area of the trapezoid is 50 square inches
<em>A) 21</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>
</em>
<em>multiples of 7 = all form numbers n×7 ; n ∈ N</em>
<em>21 = 3×7</em>
<em>29 = prime number</em>
<em>27 = 3³</em>
<em>23 = prime number</em>
<em>
</em>
<em><u>the only multiple of 7 is </u></em><em><u>21</u></em>
