Answer:
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Step-by-step explanation:
Let
x -----> number of pages that Polina read
y ----> number of pages that Marcus read
we know that
x+y=108 ----> equation A
x=5y -----> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
30
dividing the length and width by 2
10 ÷ 2 = 5 and 12 ÷ 2 = 6
he can plant 5 × 6 = 30 pumpkin plants
Yo sup??
you can solve this quesion by having the knowledge of trigonometric ratios
let angle B be x, then
tanx=7/3
x=66.8
Hope this helps
Answer:
<em> or 10.8627805 </em>
Step-by-step explanation:
Start by taking the difference of each value of both points
<u>Find the difference in x values </u>
78-2 = 76
<u>Find the difference in y values</u>
46-4 = 42
<u>Add the two differences </u>
76+42=118
<u>Take the square root of this value </u>

A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68
a=68->length
b=34->width
