Answer:

x = 7/6

Step-by-step explanation:

Solve for x:

35/74 (4/3 + 21/(5 x)) - 4/5 = 23/15

Bring 35/74 (4/3 + 21/(5 x)) - 4/5 together using the common denominator 1110 x:

(2205 - 188 x)/(1110 x) = 23/15

Cross multiply:

15 (2205 - 188 x) = 25530 x

Expand out terms of the left hand side:

33075 - 2820 x = 25530 x

Subtract 25530 x + 33075 from both sides:

-28350 x = -33075

Divide both sides by -28350:

Answer: x = 7/6

The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30

Three friends share a pizza.one eighth falls on the fall and is thrown away.the remainder is shared equally..what fraction of th

maria [59]

If one eighth of the pizza falls, that leaves seven eights of the pizza to be shared:

$1\ (whole\ pizza) -\frac{1}{8}=\frac{7}{8}$

If the 7/8 pizza is shared between three people, then you have to divide 7/8 by 3. We know that dividing a fraction by 3 is the same as multiplying by 1/3:

$\frac{7}{8} \div 3\\\\\frac{7}{8}*\frac{1}{3}\\\\\frac{7*1}{8*3}\\\\frac{7}{24}$

Therefore, each person gets 7/24 of the whole pizza.
