One number is 8 more than the other. When the larger is divided by the smaller, the quotient is 7/5

Wewaii [24]

Answer:

<h3> The numbers are 20 and 28</h3>

Step-by-step explanation:

x - the other number (the smaller one)

x+8 - 8 more than the other number (the larger number)

$\dfrac{x+8}x=\dfrac75\\\\(x+8)\cdot5=x\cdot7\\\\5x+40=7x\\^{\quad-40\qquad-40}\\{}\quad5x = 7x-40\\^{\quad-7x\quad-7x}\\-2x=-40\\^{\div(-2)\quad\div(-2)}\\{}\ \ x=20\\\\x+8=28$

The ratio table shows the costs for different amounts of bird seed. Find the unit rate in dollars per pound.

Maru [420]

Answer:

2.3 dollars

Step-by-step explanation:

Given:

Ratio table that shows the costs for different amounts of bird seed

To find: the unit rate in dollars per pound

Solution:

Amount (pounds) 5 10 15 20

Cost (dollars) 11.5 23 34.50 46

Here,

$\frac{5}{11.5}=\frac{50}{115}=\frac{10}{23}\\\\\frac{10}{23}=\frac{10}{23}\\\\\frac{15}{34.50}=\frac{1500}{3450}=\frac{150}{345}=\frac{30}{69}=\frac{10}{23}\\\\\frac{20}{46}=\frac{10}{23}$

Therefore,

$\frac{5}{11.5}=\frac{10}{23}=\frac{15}{34.50}=\frac{20}{46}$

Cost of 10 pounds = 23 dollars

So, cost of 1 pound = $\frac{23}{10}=2.3$ dollars

sasho [114]

A.
P=2(L+W)
W=29
P is at least (means greater than or equal than ) 134

so
134≤2(L+29) is the inequality

B.
solve
divide both sides by 2
67≤L+29
minus 29 from both sides
38≤L
Length is any value greater than or euqal to 38ft
