Answer:
x = 7
y = -2
Step-by-step explanation:
4x + 3y = 22 ---------------------(I)
5x - 4y = 43 ---------------------(II)
Multiply(I) by 4 and equation (II) by 3. And then add the equations
(I) * 4 16x + 12y = 88
(II) *3 <u>15x - 12y = 129</u> {Add & thus y will be eliminated}
31x = 217
x = 217/31
x = 7
Plug in the value of x in equation (I)
4*7 + 3y = 22
28 + 3y = 22
3y = 22 - 28
3y = -6
y = -6/3
y = -2
Answer:
The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound.
Step-by-step explanation:
Answer: x=6
Y=6
Step-by-step explanation:
Using the elimination method
3x+5y=48.....equ1
-3x+5y=12......equ2
Add equation 1 &2
3x+5y=48
+
-3x+5y=12
Answer =
10y=60
Y=60/10
Y=6
Substitute for y in equation 1
3x+5y=48
3x+5(6)=48
3x+30=48
3x=48-30
3x=18
X=18/3
X=6
Therefore,
X= 6
Y= 6
They are alike because you are just doubling the number by 2
Multiply by 3 so the answer is three
