Answer:
Do you have answer choices
Step-by-step explanation:
1) first slove for X ( 7y=15−<span>x) to solve this first subtract 15 from both sides -->
7y-15= -X ---> then multiply by -1 on both sides -----> -7y+15=x ( switch sides) so basically : </span>x=−7y+1<span>5
2) Then </span> Substitute x=-7y+15x=−7y+15 into 8x+4y=16 now solve steps below how to solve:
Start with the original equation ( 8x+4y=16)
Let x= -7y+15
<span>8(−7y+15)+4y=16 ----> simplify ----> −52y+120=16
Now solve for Y ( </span>−52y+120=1<span>6) steps:
</span>−52y=16−120 ( subtract 120 from both sides) & simplify by 16-120=−104
−52y=−104
now isolate Y divide both sides by -52 ----> y=2
Substitute y=2 into x=-7y+15
x= -7(2)+15
x=1
your final answer :
x=1
y=2
Answer: 32 dancers
Step-by-step explanation:
I drew a chart and on the side with the singers you count by 5's until u get to 30. On the dancers side of the chart you count by 6's until it lines up with 30 on the singers side.
The answer is the A :)
30*3 and you'll get the number of minutes Reggie walked
Answer:
3, 6, 7, 10, 11
Step-by-step explanation:
The angles congruent to angle 1 are the corresponding angles and their vertical angles.
The corresponding angles are the ones on the north-east corner of the intersection: 1, 7, 11
The angles that are vertical angles with those are ...
3, 6, 10
So, the angles congruent to angle 1 are 3, 6, 7, 10, 11.
