Answer:
Base of figure A = 12 units
Step-by-step explanation:
Given:
Base of figure B = 15 units
Ratio of figure A to figure B = 4:5
Find:
Value of X
Computation:
X / 15 = 4 / 5
x = 4(15) / 5
x = 12
Base of figure A = 12 units
Answer: z = 
<u>Step-by-step explanation:</u>
67a(t + z) = 45z + 67
67at + 67az = 45z + 67
<u>-67at -45z </u> <u>-45z -67at </u>
67az - 45z = 67 - 67at
z(67a - 45) = 67 - 67at
<u>÷ (67a - 45) </u> <u>÷ (67a - 45) </u>
z = 
=

Answer:
Elimination
x = 2
y = -2
Step-by-step explanation:
Elimination
2x + 4y = -4
2x - y = 6
Subtract the second equation from the first
5y = -10
Divide both sides by 5
y = -2
---------------------
Substitute for y = -2 in the second equation
2x - -2 = 6
2x + 2 = 6
subtract 2 from both sides
2x = 4
Divide both sides by 2
x = 2
Answer:
<h2><u><em>
n = 8</em></u></h2>
Step-by-step explanation:
2n + 1.6 = 17.6 what is the value of n?
2n + 1.6 = 17.6
2n = 17.6 - 1.6
2n = 16
n = 16 : 2
n = 8
-----------------
check
2n + 1.6 = 17.6
2*8+1.6=17.6
16+1.6=17.6
17.6=17.6
the answer is good
