Match the equation with its corresponding solution for x: 4x+7=35

1 answer:

7 0

4x+7=35
4x=28
x=7

A corresponding solution of the matching equation is a fancier way of telling you to find the number that represents x

Divide the sum of -13/5 and 12/7 by the product of -31/7 and -1/2

andriy [413]

Let's compute the two factors separately: as for "the sum of -13/5 and 12/7", we have to rewrite the two fractions so that they have the same denominator. Since the least common multiple of 5 and 7 is 35, we will change both fractions so that they have denominator 35:

$\frac{-13}{5} = \frac{-13}{5}\frac{7}{7} = \frac{-91}{35} \qquad \qquad \frac{12}{7} = \frac{12}{7}\frac{5}{5} = \frac{60}{35}$

So now we can sum them:

$\frac{-13}{5}+\frac{12}{7} = \frac{-91}{35}+\frac{60}{35} = \frac{-91+60}{35} = \frac{-31}{35}$

Multiplication is easier, since you just have to multiply numerators and denominators with each others:

$\frac{-31}{7} \frac{-1}{2} = \frac{-31 \cdot (-1)}{7\cdot 2} = \frac{31}{14}$

Finally, we must divide the two fractions. Dividing by a fraction is the same this as multiplying by the inverse of that fraction, i.e. we have to switch numerator and denominator:

$\frac{-31}{35} \div \frac{31}{14} = \frac{-31}{35} \cdot \frac{14}{31} = -\frac{2}{5}$

A team of ranger marked 24 squirrels in a park. Later, a class counted 480 squirrels, 16 of which were marked. To the nearest wh

Hitman42 [59]

Answer: 720

Step-by-step explanation:

480 : 16 marked

480-16 = 464

They saw 464 unmarked squirrels and 16 marked squirrels

464/16 = 29

They saw 29 unmarked squirrels for every 1 makes squirrel

29 * 24 = 696

They would have seen 696 unmarked squirrels for the 24 marked squirrels.

696 + 24 = 720
