Answer:

B = 119°

C = 119°

Step-by-step explanation:

The value of back to back angles are the same when the lines are straight.
Therefor there are two 61° they add together to make 122°
You can then subtract 122 from 360 to get 238.
Then take 238 and divide it by 2, to get your answer which is 119° for both.

Answer:

'b' and 'c' = 119 degrees

Step-by-step explanation:

Given that this is a basic intersection of straight lines, we can assume 'b' and 'c' are equal as well as the given angle and it's opposite. Given 61 degrees and and two straight lines we can just take 180 degrees - 61 degrees and we get 119 degrees, I solved for 'b', but this will give the same answer for 'c', as 'b' and 'c' are equal.

Paul's mom sent him to the grocery store with $10 to buy bread and cheese for sandwiches. Paul picked out a loaf of bread that c

lutik1710 [3]

Given:

Total amount = $10

Cost of loaf of bread = $3.25

Cost of cheese = $5.99 per pound

Each slice weights = 0.04 pounds.

To find:

The inequality for the number of slices that Paul can afford to buy.

Solution:

Let x be the number of slices that Paul can afford to buy.

Weight of on slice is 0.04 pounds. So, weight of x slices is 0.04x pound.

Cost of cheese = $5.99 per pound

So, total cost of cheese for x slices = $5.99 × 0.04x

Now, Paul has $10 to buy bread and cheese for sandwiches. Cost of loaf of bread is $3.25.

$3.25+(5.99\times 0.04x)\leq 10$

$0.2396x\leq 10-3.25$

$0.2396x\leq 6.75$

Divide both sides by 0.2396.

$x\leq \dfrac{6.75}{0.2396}$

$x\leq 28.172$

The maximum integer value of x is 28.

Therefore, the required inequity is $3.25+(5.99\times 0.04x)\leq 10$ and 28 number of slices Paul can afford to buy.

You have $30 to spend on gas for your vehicle this week. If gas costs $2.42 per gallon, how many gallons of gas can you buy? Rou

Eva8 [605]

12 gallons of gas can be bought from $30 where gas costs $2.42 per gallon.

Solution:

The gallons of gas bought can be calculated by dividing the total amount possessed by cost of gas per gallon.

Here total amount possesses is $30 and cost of gas per gallon is $2.42.

Gallons of gas bought = $\frac{Total\ amount\ possessed}{Cost\ of\ gas\ per\ gallon}$

$\bold{\frac{30}{2.42} = 12.3966 = 12}$

) a) Liaqat gave his uncle a puzzle. "five times my age plus 10 years makes 70 years." How old is Liaquat? b) His uncle replied,

Kamila [148]

Answer:

a. 12 years

b. 30 years

Step-by-step explanation:

a) Assume Liaqat's age is x. His age would be:

5x + 10 = 70

5x = 70- 10

x = (70 - 10) / 5

x = 12

Liaqat is 12 years old.

b. Assume his uncle's age is y;

4y - 10 = 130

4y = 130 - 10

y = (130 - 10) / 4

y = 30

Liaqat's uncle is 30 years old.
