If you pay $107 for groceries including tax, what is the price of groceries before tax when you are taxed at 7%?

timofeeve [1]

Answer:

100

Step-by-step explanation:

Original price: x

x + (7%*x) = 107.

107 is 107% of the original price

107 = 1.07x

Divide by 1.07 on both sides

x = 100

Check:

7% of 100 is 7

100 + 7 = 107

Hope this helps :)

Solve the following simultaneous equation using either the substitution method or the elimination method, showing all the necess

slavikrds [6]

Answer:

$x=1\frac{83}{91}\\y=-2\frac{73}{91}$

Step-by-step explanation:

#Using the method of substitution and replacement of unknown values.

Given that

$\frac{3}{2}x+\frac{2}{3}y=1...(i)\\and\\\frac{1}{6}x-\frac{3}{5}y=2...(ii)\\$

Express eqtn (ii) in terms of x

$\frac{1}{6}x=2+\frac{3}{5}y\\x=12+\frac{18}{5}y$

Replacing for x in eqtn (i)

$\frac{3}{2}(12+\frac{18}{5}y)+\frac{2}{3}y=1\\18+\frac{27}{5}y+\frac{2}{3}y=1\\18-1=-\frac{91}{15}y\\y=-2\frac{73}{91}$

Substitute y value in eqtn(ii) to obtain x

$Y=-2\frac{73}{91}\\\frac{1}{6}x-\frac{3}{5}y=2\\x=2+\frac{3}{5}(-2\frac{73}{91})\\x=1\frac{83}{91}$

The ratio of girls to boys in he 6th grade is 6 to 7. How many girls are there if there are 364 total students

inn [45]

If the ratio is 6:7 the students should divide nicely into 6+7=13 parts. Six of those parts are girls, seven of those parts are boys.

364 / 13 = 28

So 6 × 28 = 168 girls

Answer: 168

Check:

7 × 28 = 196 boys

168 + 196 = 364, good
