How to solve -2(-4f+5)=-7+2f-9

Answers

Answer 1

Answer:

[tex]f=\frac{3}{5}[/tex]

Step-by-step explanation:

[tex]-2(4f+5)=-7+2f-9[/tex]

First, use PEMDAS to distribute the -2 to the parenthesis.

[tex]-8f -10 = -7+2f -9[/tex]

Combine like terms on the right side.

[tex]-8f - 10 = -16+2f[/tex]

Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.

[tex]-8f = -6 + 2f[/tex]

Now subtract the 2f from both sides.

[tex]-10f = -6[/tex]

Divide both sides by 10.

[tex]f = \frac{-6}{-10}[/tex]

Simplify.

[tex]f = \frac{3}{5}[/tex]

Answer 2

Answer:

The value of f:

[tex]f=-1[/tex]

Step-by-step explanation:

Given the expression

[tex]-2\left(-4f+5\right)=-7+2f-9[/tex]

Group like terms

[tex]-2\left(-4f+5\right)=2f-7-9[/tex]

Subtract the numbers: -7-9=-16

[tex]-2\left(-4f+5\right)=2f-16[/tex]

Expand:  -2(-4f + 5) = 8f - 10

[tex]8f-10=2f-16[/tex]

Add 10 to both sides

[tex]8f-10+10=2f-16+10[/tex]

Simplify

[tex]8f=2f-6[/tex]

Subtract 2f from both sides

[tex]8f-2f=2f-6-2f[/tex]

Simplify

[tex]6f=-6[/tex]

Divide both sides by 6

[tex]\frac{6f}{6}=\frac{-6}{6}[/tex]

Simplify

[tex]f=-1[/tex]

Therefore, the value of f:

[tex]f=-1[/tex]

The answer is the last one.

Step-by-step explanation:

Firstly, look at the first inequality and we get [tex]4x+5<13[/tex], so [tex]x<2[/tex]. In the second inequality, we have [tex]15\leq 2x[/tex], so [tex]x\ge 7.5[/tex]. Together, we know that the answer is the last one.

• The shortest side of a triangle is 8 centimeters long. The longest side is 8 cm longer than the
shortest side. The third side is 12 cm long. The perimeter is 38 cm. Find the length of the
shortest side.

Answers

The shortest side is 9, longest is 17 of the triangle IS NOT a 90 degree triangle

Answer:

9cm

Step-by-step explanation:

s + s + 8 + 12 = 38

(s + s) + (8 + 12) = 38

2s + 20 = 38.

so, we have to subtract 20 from both sides, so it will be 2s = 18.

2s/2 = 18/2. so that means, s = 9.

hope this will help you!

What is the probability of spinning a odd number, flipping heads, then spinning a 3?

Answers

Answer:

Probability of spinning a odd number is 5/9

I don't know about flipping head

Probability of spinning a 3 is 1/9

Answer:   0

=========================================================

Explanation:

The sample space of the spinner is {1,2,3,4,5,6,7,8,9} which represents all the possible outcomes. We can only pick one of those values. Of that list, the subset {1,3,5,7,9} represents all the odd numbers. This is the event space because we want to land on an odd number.

There are 5 items in the event space and 9 items in the sample space. The probability of getting an odd number is 5/9.

The probability of flipping heads is 1/2 since we have one side we want (heads) out of two sides total.

Lastly, the probability of landing on a '3' is 1/9 because there's only one '3' out of 9 values total.

---------

We'll multiply those fractions to get the final answer. This works because each event is independent of one another.

(5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Now use your calculator to find that: 5/162 = 0.030864 approximately which rounds to 0.0 or just 0 when rounding to the nearest tenth.

Unfortunately this is one case where rounding will creates a misleading result. The true probability isn't 0 because the events described are possible. The probability is just really small.

1.1x - 2 = 9.1 what is x

Answers

Simplifying
1.1x + 8 = 9.1

Reorder the terms:
8 + 1.1x = 9.1

Solving
8 + 1.1x = 9.1

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.
8 + -8 + 1.1x = 9.1 + -8

Combine like terms: 8 + -8 = 0
0 + 1.1x = 9.1 + -8
1.1x = 9.1 + -8

Combine like terms: 9.1 + -8 = 1.1
1.1x = 1.1

Divide each side by '1.1'.
x = 1
