Simply (2)/(3)a+6-(3)/(5)a-1

Bas_tet [7]

Answer:

That simplifies to $\frac{1}{15}a + 5$

Step-by-step explanation:

Let's simplify:

$\frac{2}{3}a + 6 - \frac{3}{5}a - 1\\\\\frac{10}{15}a - \frac{9}{15}a + 6 - 1\\\\\frac{1}{15}a + 5$

If you want to express that as a single fraction, you can do so by multiplying the five by 15/15, and summing the numerators. That gives you:

$\frac{a + 75}{15}$

Blake has a graden in his back yard. He picked 55 tomatoes from 5 plants. what is the ratio of tomato plants tomatoes picked?

oksian1 [2.3K]

Answer:

Step-by-step explanation:

he picked 11 tomatoes per plant, 55 ÷ 5 = 11 so all answers that dont include an 11 are incorrect, A and C are wrong

because the tomato plants are listed before the tomatoes picked in the ratio that means that the number of plants has to be first, and the number of tomatoes has to be second. that means the answer is D, 1 plant: 11 tomatoes

Find the missing length of the following trapezoid

Schach [20]

Answer:

1) The length of $DC$ is 20.

2) The length of $PS$ is 17.

Step-by-step explanation:

1) If $DR = RE$ and $CS = SB$ , then we can use the following proportionality ratio:

$\frac{DE}{DR} = \frac{32 - x}{26 - x}$ (1)

Where $x$ is the length of segment $\overline{CD}$ .

If $DE = 2\cdot DR$ , then the value of $x$ is:

$2 = \frac{32-x}{26-x}$

$52 - 2\cdot x = 32 - x$

$20 = x$

The length of $DC$ is 20.

2) If $QV = VP$ and $RW = WS$ , then we can use the following proportionality ratio:

$\frac{QP}{QV} = \frac{x-7}{12-7}$ (2)

Where $x$ is the length of segment $\overline{PS}$ .

If $QP = 2\cdot QV$ , then the value of $x$ is:

$2 = \frac{x-7}{5}$

$10 = x-7$

$x = 17$

The length of $PS$ is 17.
