Answer:
5
Step-by-step explanation:
6 - 3 = 3
√4 = 2
3 + 2 = 5
Answer:
4
9/8
Step-by-step explanation:
Given the fraction a/b, the reciprocal is expressed as 1/(a/b) = b/a
For 1/4;
1/4
= 1÷1/4
= 1 * 4/1
= 4
Hence the reciprocal is 4
b) 8/9
= 1 ÷ 8/9
= 1 * 9/8
= 9/8
Hence the reciprocal of 8/9 is 9/8
Step-by-step explanation:
5x+52=9x+20
subtract 5x on both sides
subtract 20 on both sides
32=4x
divide by 4 on both sides
x=8
plug in x to the equations for A, D, and C
A and D are 92°
C is 56°
B and C will add up to 90, so
90-56=34°
13y-6=34
add 6 on both sides
13y=40
divide by 13
y=40/13 (I don't wanna calculate that)
-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
