A pair of equations is shown below:

1 answer:

4 0

I would use subsitution because both are already equal to a single variable

set both equal since both equal y
8x-9=y=4x-1
8x-9=4x-1
minus 4x both sides
4x-9=-1
add 9 boh sides
4x=10
divide by 4
x=10/4=5/2
sub for x

y=4x-1
y=4(10/4)-1
y=10-1
y=9

(5/2,9) is solution

A. work shown above
B. (5/2,9) or (2.5,9)

Is 35% more than 2/5

eduard

If you convert 2/5 into a decimal which is 0.4 and multiply it by 100
you'll get 40 which means 2/5 is 40%
so 35% is less than 2/5

Add 1/10 + 2/15 (show steps pls-) :)

Ksivusya [100]

Answer:

$\frac{7}{30}$

OR...

0.233333333

Step-by-step explanation:

Least common multiple of 10 and 15 is 30. Convert $\frac{1}{10}$ and $\frac{2}{15}$ to fractions with denominator 30.

$\frac{3}{30} +\frac{4}{30}$

Since $\frac{3}{30}$ and $\frac{4}{30}$ have the same denominator, add them by adding their numerators.

$\frac{3+4}{30}$

Add 3 and 4 to get 7.

$\frac{7}{30}$

Answer: The answer is C

Step-by-step explanation:

Point G and H are the same distance from point F

If the distance from Point G to Point F is 3 units Point F has to be 3 units away from Point H. (5,2) is the only coordinate that is 3 units away.
