4 13/ 25 as a decimal
slavikrds [6]

Turn the fraction into an improper fraction.

4 13/25 -> 113/25

Divide both numbers.

113 / 25 = 4.52

Best of Luck!

Eric estimated 28x48 by finding 30x50. His estimate was 1,500,but he says the actual product will be greater than that amount.Is
Aloiza [94]

Answer:

Eric is not correct.

Step-by-step explanation:

We have been given that Eric estimated 28\times 48 by finding 30\times 50. His estimate was 1500, but he says the actual product will be greater than that amount.

To find if Eric is correct or not, let us see how to estimate an answer.

While estimating our given numbers we will round to nearest tenth and change the digit to the right of the rounding place to 0.

As 8 is greater than 5, so we will round 28 to 30 and 48 to 50.

Since we are rounding up, so our estimated answer will be greater than actual answer, therefore, Eric is not correct.

Will mark brainlist or whatever (word in blue says miles btw if you couldn’t read it)
valentina_108 [34]

Answer:

y = 2.75x + 7.5 | 10 miles

Step-by-step explanation:

the equation would be like this, y = ax + b

29.5 = 2.75(8) + b, b = 7.5 so the sub charge is 7.5

therefore the equation is y = 2.75x + 7.5

.

35 = 2.75x + 7.5 , x = 10 miles
