Answer:
∠ IGJ = 52°
Step-by-step explanation:
Given ∠ EGD = 38° , then
∠ DGF = 90° - 38° = 52° ( sum of angles is 90 ), thus
∠ IGH = 52° ( vertical to ∠ DGF )
Answer: he needs $21.50
Step-by-step explanation:
You have to add 22+50=75 then add 15 more to 75 which equals 90....after that you have to divide 7 in half and get 3.5 so now you have to add 90+3.5 and get 93.5. Now you must subtract 93.5-65 and get 28.5 and lastly you subtract 50-28.5 to find out how much money if let to buy VANS.
Answer:
<em><u>0=x</u></em>
Step-by-step explanation:
First you need to get the variable on one side of the equation
7-x+3=9x+10
+x +x
7+3=10x+10
Now we can combine like terms on the left side of the equation
10=10x+10
Subtract 10 from each side
10=10x+10
-10 -10
0=10x
Divide by 10
0 =10x
/10 /10
<em><u>0=x</u></em>
Answer:
3
Step-by-step explanation:
The opposite of -3 is 3.
Since you are given a list of choices, you can go through each choice to plug them into the equations. It turns out that choice B is the answer
(3,1) means that a = 3 and b = 1
Plug in a = 3 and b = 1 into the first equation
2a - 5b = 1
2*3 - 5*1 = 1.... replace 'a' with 3, replace b with 1
6 - 5 = 1
1 = 1
we get a true equation, so we have confirmed the first equation
Do the same for the second equation
3a+5b = 14
3*3+5*1 = 14 .... replace 'a' with 3, replace b with 1
9+5 = 14
14 = 14
we get a true equation, so the second equation has been confirmed
Both equations are true when (a,b) = (3,1). So the answer (3,1) has been confirmed fully
