Dimas [21]2 years ago

Answer:

24.3

Step-by-step explanation:

We need to follow the order of operations PEMDAS:

  • Parentheses
  • Exponents
  • Multiplication and Division (from left to right)
  • Addition and Subtraction (from left to right)

Carry out the operation in the parentheses first:

   3³ + 14.7 ÷ 7 - (1.2 × 4)

⇒ 3³ + 14.7 ÷ 7 - 4.8

Now the exponent:

⇒ 3³ + 14.7 ÷ 7 - 4.8

⇒ (3 × 3 × 3) + 14.7 ÷ 7 - 4.8

⇒ 27 + 14.7 ÷ 7 - 4.8

Now, the division (there is no multiplication):

⇒ 27 + 14.7 ÷ 7 - 4.8

⇒ 27 + 2.1 - 4.8

Finally, carry out the addition and subtraction (from left to right)

⇒ 27 + 2.1 - 4.8

⇒ 29.1 - 4.8

⇒ 24.3

A line passes through the point (-8,9) and has a slope of 5/4.
Masteriza [31]

Answer:

The answer is

<h2>y =  \frac{5}{4} x + 19 \\</h2>

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (-8,9) and slope 5/4

The equation of the line is

y - 9 =  \frac{5}{4} (x + 8) \\  y - 9 =  \frac{5}{4} x + 10 \\ y =  \frac{5}{4} x + 10 + 9

We have the final answer as

y =  \frac{5}{4} x + 19 \\

Hope this helps you

Y=x<br> 8x+2y=70<br> How do you solve this
Igoryamba
First you subtract 8x to both sides so you get
2y=-8x+ 70
then you divide 2 with everything to get y by itself
-4x+35=y

3/4x+5−1/2x=3 what is the value of x?
dimaraw [331]

Answer:

-1/8 is the answer

Step-by-step explanation:

1.) 1st we have to take 1/2x and make the bottom number 4. so we multiply by 2 and you should get 2/4.

2.) so now the equation should be 3/4x + 5 -2/4x = 3. now you take 3/4x and -2/4x and subtract them and you should get 1/4x.

3.) now the equation should look like 1/4x + 5 = 3. now we need to get all whole numbers to one side. so we will subtract 5 from 5 and that will cancel it out and we need to do that to both sides. so we will subtract 5 from 3 and you will get -2.

4.) now the equation should look like 1/4x = -2. now you put a 1 under the 2 to make it a fraction. it should look like 2/1 and then you are going to flip it because that is how you divide fractions. so now your equation should look like 1/4x = 1/2. now you multiply strait across both bottom and top. and you will get x = -1/8 and that is your answer.

hope this helped!

p.s it would be cool if you gave me brainliest.

The letters that form the word ALGEBRA are placed in a bowl. What is the probability, as a percent, of choosing a letter other t
KonstantinChe [14]

It will be 2/42 you count out the letters in “ALGEBRA” and then you can the A’s which equal a fraction 2/7 then you subtract 1 from the numerator and the denominator which then equals  1/6. Then you multiply the fractions and get 2/42
