7(4+5+2)-6(3+5) evaluate the expression

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

7(4 + 5 + 2) - 6(3 + 5)

First we need to know what PEMDAS is. It is an acronym that helps remind you what steps to take when evaluating any kind of equation or expression.

P-arentheses
E-xponents
M-ultiplication
D-ivision
A-ddition
S-ubtraction

In PEMDAS, multiplication/division and addition/subtraction are in no particular order-- they are solved from left to right.

Knowing what PEMDAS means, you can start evaluating the expression. Start by solving inside the parentheses, as PEMDAS tells you to do.

Add 4 + 5 + 2 and 3 + 5 inside of the two parentheses in the expression.

7(11) - 6(8)

Since there are no exponents, you can skip this step and move on to multiplying 7 * 11 and 6 * 8.

(77) - (48)

The final process in evaluating this expression is to subtract 48 from 77.

29 is your answer.

Answer 2

Answer:

Answer:

7(11) -6(8)

77-48=29

7. What is the value of t?
t=

Answers

Answer:

t = -3

Step-by-step explanation:

To answer this problem, first you have to know how to calculate the slope of a line. Since we know that y1-y2/x1-x2 is the equation to calculate slope, we are ready to tackle this problem.

Because y1 is t, y2 is 4, x1 is 4, and x2 is 5, we can now plug this in to our equation. The equation becomes t-4/4-5. And because we know the slope is 7, the equation is now (t-4)/(4-5)=7. If you solve this equation, you will get that t=-3

Darius takes his family on an afternoon boat ride. Going through York Canal, he drives 5 miles in 15 minutes. Later on as he crosses Stover Lake, he drives 30 minutes at the same average speed. Which statement about the distances is true? A) The distance traveled in York Canal is 15 miles less than the distance traveled on Stover Lake. B)The distance traveled in York Canal is twice the distance traveled on Stover Lake C)The distance traveled in York Canal is one half the distance traveled on Stover Lake. D)The distances traveled in York Canal and Stover Lake are the same.

Answers

In first case, the average speed is (5/15) miles per minutes = (1 /3 ) miles per minutes;
In second case, the distance traveled in York Canal is 30 x ( 1 / 3) = 10 miles;
But, 10 + ( 10 ÷ 2 ) = 10 + 5 = 15 miles;
The correct answer is C)!

Answer:

The distance traveled in York Canal is one half the distance traveled on Stover Lake.

What is the coefficient of z in the expression 3x + 2y + z?

Answers

the coefficient is 1. 1z = 1*z = z.

You are given the expression 3x + 2y + z

It is clear that coefficient of x is 3 and y is 2. But there is nothing written with z.

So what is the coefficient of z?

When there is no number written before a variable, then its coefficient is 1.

Coefficient is always muktiplied with the variable. So z = 1×z = 1z. But we generally do not write 1 before a variable.

So coefficient of z is 1.

there 176 slices of bread in 8 loaves. if there are the same number of slices in each loaf, how many slices of bread are in 5 loaves?

Answers

176 ÷ 8 = 22

So,

In 1 loaf of bread there is 22 slices of bread.

5 × 22 = 110

SO

there r 110 slice of bread in 5 loaves.

Hope I helped ya!

There is 110 slices of bread total in 5 loaves.
170/8=22
22*5=110
