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:
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]Identify the graph of the inequality 2(2x - 1) + 7 < 13 or -2x + 55-10.

Answer:
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.
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!

Solve x^2-4=0 please solve step by step
Answer:
x=2 or x=−2
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−4=0
Step 1: Add 4 to both sides.
x2−4+4=0+4
x2=4
Step 2: Take square root.
x=±√4
x=2 or x=−2

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

There is a square pyramid in Egypt that has a volume of 67,600 cubic meters. If the side length of the base is 52 meters, how tall is this Egyptian pyramid?
Answer:
The pyramid would be 3,900 meters tall
Step-by-step explanation:
if you take the formula V=1/3bh your equation should look like this - 67600=1/3(52)h You then multiply and divide until you have gotten 3900.

5a - 2 = 23
Answer:
5a - 2 = 23
Add 2 to both sides
5a -2 + 2 = 23 + 2
Add 23 + 2 you will get 255a = 25
Divide both sides by 55a/5 = 25/5
a = 5 as the answer
