Answer:
m∠A = 139°
Step-by-step explanation:
First we must know that
Supplementary angles equal to 180 degree.
Since we know that supplementary angles equal to 180 degree we can solve now:
Putting m ∠A and m ∠ B together and put the = 180
( 7x - 15 ) + ( 2x - 3 ) = 180
Now solving for x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Hence, Angle A will have a measure of 7x - 15 which means 7 × 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°
139 + 31= 180

The correct question is
<span>John mixed 3/4 liter of yellow paint with 1 1/4 liters of red paint to make 2 liters of orange paint. • He needed more orange paint. • To make a new batch of orange paint, he used exactly 1 liter of red paint. Using the same ratio, how many liters of yellow paint should John use to make the new batch of orange paint?
we know that
yellow paint---> 3/4 liters
red paint-----> 1 1/4 liters-----> (1*4+1)/4-----> 5/4 liters
ratio=yellow paint/red paint-----> (3/4)/(5/4)---> 3/5
if h</span>e used exactly 1 liter of red paint
<span>so
3/5=x/1------> x=3/5 liters of yellow paint
the answer is
</span>3/5 liters of yellow paint<span>
</span>
Answer:
The answer is (6,9)
Step-by-step explanation:
We simply need to find two numbers that perfectly fits the equation. That is, 2 numbers in which when we substitute the value for x and y works perfectly.
First option is wrong.
3x + 2y = 36
Here, x = 6 and y = 0
Hence, 3(6) + 2(0) = 18 which is wrong.
3rd option is wrong
Here x = 6 and y = -9
3(6) + 2(-9) = 0
Last option is wrong
Here x = 6 and y = 6
3(6) + 2(6) = 18 + 12 = 30.
2nd option is correct
Here x =6 and y = 9
3(6) + 2(9) = 18 + 18 = 36
Hey, did you get the expressions for both figure A and B? If so could you pls write them down below.
It is
log 39=2
Explanation:
By definition the logarithmic form
log bx=y is equivalent to the exponential form
by=x
Hence from the given 32=9 you have b=3 , y=2 , x=9
hence the logarithmic form is
log 3 9=2
