Step-by-step explanation:
7 x 3 = 21
It means try to figure out the question by using the things with the same variable. so if it says “x + 6 = 13 and x = 8 then you use the x = 8 to figure out x + 6 = 14
Step-by-step explanation:
y=kxz
13=k x 5 x 8
13= 40k
K=13/40
a. y=13/40 x 4 x 10
y=13/40 x 40
y=13
b. 20=13/40 x x x 12
20=13/40 x 12x
20=<u>156x</u>
40
20 x 40=156x
800=156x
X=<u>800</u>
156
X=<u>200</u>
39
X=5 5/39
C. 15=13/40 x 6 x z
15=<u>78z</u>
40
15x40=78z
600=78z
Z=<u>600</u>
78
Z=<u>100</u>
3
Z=7 9/13
