Hel What is the value of the expression 7 + (16 − 7) ÷ 3 + 8? worth 10 points a. 12
b. 15
c. 17
d.18

d 18

Step-by-step explanation:

Given expression

7 + (16-7) ÷ 3 + 8

= 7 + 9 ÷3 + 8

= 7 + 3 + 8

= 18

Hope it will help :)

d. 18

Step-by-step explanation:

We are given an expression and are asked to solve, when solving, we need to follow the PEMDAS rule. Commonly used when so many factors and signs are at hand.

PEMDAS -

Parenthesis

Exponents

Multiply

Divide

Addition

Subtraction

This rule is showing what to do first when you have long expressions like these, do as followed and solve the parenthesis first :

7 + (16 - 7) / 3 + 8

7 + 9 / 3 + 8

Now divide :

7 + 9 / 3 + 8

7 + 3 + 8

Now that we only have to add, add all numbers together :

7 + 3 + 8

18

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
