1)4x-7=2x+9
Subtract 2x
2x-7= 9
Add 7
2x=16
X= 8
2(8)+9=25
(8,25)
X+y=10
-X-2y=-14
-y= -4
Y=4
X+4=10
X=6
(6,4)
<h2>(-7) x (-3) =<u> 21</u></h2>
.... Hope this will help....
Answer:
more than 7
Step-by-step explanation:
4+3 = 7

To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
Answer:
X= 32 Y= 35
Step-by-step explanation:
We know FOB is parralel to AOE meaning x= 32
also, COH = 90 so GOD is also 90.
a straight angle is 180, so
23+90+x or 32= 145,
180-145=35,
y=35
