Answer:
The expressions a(8x+7) and 4x + 3.5 are equivalent
Therefore, according to the above problem the equation is :---

By comparing the term, we get

and,

<h3>The value of "a" is <u>1/2</u>.</h3>
First: perform the operation in the parentheses
Second: evaluate 3 (2)
Third: divide 8 by 2
Fourth: Add 4 and 9
Not sure if that’s right or not since i havent done this in 2 years but i tried <3 good luck
Answer:
x=81°
Step-by-step explanation:
The sum of all angles in a triangle is 180°
57+42=99
180-99=81
Answer:
1) N5.00
2) N1.50
Step-by-step explanation:
1) 1/2+1/4+1/5=10/20+5/20+4/20=19/20=95%
That means the 4th girl received 5%.
25 is 5% of 500
500 Kobo is N5.00
2) He lost 55%, so they means he has 45% left.
67.5 is 45% of 150
(67.5/0.45=150)
150Kobo is N1.50
the length of SR is
.
<u>Step-by-step explanation:</u>
Here we have , On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) . We need to find Length of side SR . Let's find out:
We know that , In a square there are 4 sides , and length of every side is same . So side length of SR = side length of QR . Now , Let's find side length of QR .
We know that distance between two points
given by :
⇒ 
Two points given are
:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
But QR=SR , Therefore , the length of SR is
.
