Candice's mother gave her $75.38 to go to the store. Candice bought
4 loaves of bread and 3 cartons of orange juice. Each loaf of bread cost
$2.45 and each carton of orange juice cost $4.55. How much money
does Candice have left?

Answers

Answer: Candice has $51.93 left after going to the store

Step-by-step explanation:

4 loaves of bread cost $9.80 and 3 cartons of orange juice cost $13.65. In total it cost $23.45. $75.38 - $23.45= $51.93

Answer:

Candace would have $51.93.

Step-by-step explanation:

The four loaves of bread would cost $9.80

The three cartons of juice would cost $13.65

Add these up and we get $23.45

Subtract this from $75.38, and we get the answer of $51.93

Answers

the answer is 136 :)

first u should find the area of rectangular:

7 × 16 = 112

then u should find the area of triangular:

Altitude = 13- 7 = 6

base=16 - 8 = 8

so...u can find the area of triangular now:

(6× 8)÷2 = 48 ÷ 2 = 24

so...the area of your shape is: 112+ 24 = 136

Answers

Answer:

x = 6

Step-by-step explanation:

10 - 4 = 6

The x means the number is unkown, well, we know that 6+4=10, so there you go!

Answer:

6

Step-by-step explanation:

x is a mystery number. We don't know what it is, but we know that if you add 4 to it, we get 10. To what number should we add 4 to get 10?

That's right, 6.

A more advanced explanation:

We need to isolate x, so it will be alone on one side of the equation. To do this, we must subtract 4 from the left side of the equation, so it will be x + 0, or x. But we also need to remember that equations always need to be balanced, so we need to subtract 4 from both sides, to get x + 0 = 10 - 4. Simplifying, we get that x = 6.

Hope this helps!

write a list of steps that are needed to find the measure of ∠B.

Answers

it’s subtraction, so you must subratct 113 by 72, then your answer will be B= 41

so you start with taking 180-113 because that straight line is made up of 2 angles that equal 180, you’ll get 67 then the three angles of a triangle will add up to 180 so you’ll do 67+72=139 and subtract that from 180 to find your missing angle which is 180-139=41 so

Answer:

a. t = I/Pr

b. The value of t in the table is 3 years

Step-by-step explanation:

Solve for t in the formula.

I = Pr

~Divide pr to both sides

I/Pr = t

Using the formula above, we can solve for t.

75/(500)(0.05) = t

75/25 = t

3 = t
