Answer:

12.

Step-by-step explanation:

This equation seems to want you to use the Order of Operations, a.k.a PEMDAS (which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). When you do a problem like this, you use the Order of Operations to figure out the order in which you'd solve your problem.

You would first solve what is in parentheses, since that is the first letter in PEMDAS. 18-6x2 is what we have in our parentheses, but it's too confusing to be solved yet. The next letter is E, a.k.a exponents, but there are no exponents in this equation, so we move on. Next is M, Multiplication. We would multiply 6 by 2, which gives us 12. Moving on, we have D, Division. We would do 36/6, which is 6.

Our 5th letter is A, Addition. We would have to add our 6 to (18-12), but that couldn't work, since our 18-12 is still in parentheses, and those come first. So, we would skip to the last letter, S, Subtraction. 18-12=6, and since we solved all the problems in the parentheses, we remove them, and add both 6's together, giving us 12.

3. Solve the equation. -3 2/5 + b = 8 1/5

user100 [1]

Answer:

3) b= 11 3/5

4) n= 1/18

5) 5/12 feet

Step-by-step explanation:

3) add -3 2/5 to both sides

4) multiply both sides by 3n, divide by -42, then divide 7/42 by 3 (or multiply it by the reciprocal: 1/3)

5) convert the height to inches by multiplying by 12, subtract 69 from 74, then divide answer by 12

The two triangles are similar. What is the value of x? Enter your answer in the box. x = Two right triangles, one smaller than t

inysia [295]

x = 4
Given the description of the triangles, you have 2 similar right triangles. The smaller triangle has a height of 20 and a base of 3x, while the larger has a height of (20+8) = 28 and a base of 4x + 2. We wish to determine the value of x. Since the triangles are similar, the ratio of corresponding sides will be a constant. So:
20/28 = (3x)/(4x+2)
(4x+2)20/28 = (3x)
(20/28)*4x+(20/28)*2 = (3x)
(80/28)*x+(40/28) = (3x)
(20/7)*x + 4/7 = 3x
4/7 = 3x - (20/7)*x
4/7 = (21/7)x - (20/7)*x
4/7 = x/7
4 = x
So the value of x is 4.

When solving -1/8 (x + 35) = −7, what is the correct sequence of operations?

mariarad [96]

ANSWER:

Division, multiplication, addition is the correct sequence of operations for solving $-\frac{1}{8}(x+35)=-7$

SOLUTION:

Given, equation is $-\frac{1}{8}(x+35)=-7$

We need to solve the given equation in correct sequential order.

So, let us follow the BODMAS rule.

BODMAS means sequence of operations are brackets, orders, division, multiplication, addition, subtraction

Now,

$-\frac{1}{8}(x+35)=-7$

As the term in brackets cannot be processed further we can go for next term.

Now the division operation has to be done first according to BODMAS

- 0.125(x+35)= -7

Multiplication comes second in order.

-0.125x+4.375= -7

On rearranging the terms, we get

-0.125x+4.375+7=0

Now perform addition according to BODMAS

-0.125x+11.375=0

0.125x=11.375

$x=\frac{11.375}{0.125}=91$

Hence division, multiplication, addition is the correct sequence of operations for solving $-\frac{1}{8}(x+35)=-7$
