Answer:
7 is the answer.
Step-by-step explanation:
In equations like this, you would solve the numbers in the parenthesis first, and then gradually do: Multiplication -> Division -> addition -> subtraction.
Therefore, -18 / 9 is -2.
-2 * 2 would be -4,
11 + (-4) would be 7.
Answer : 7.
Give two reasons why this shape is a square when x=5.
Answer:
First of all, we can see that this shape have 4 90° angles.
Secondly, since x = 5 we have:
3 × 5 -2 = 15 - 2 = 13 (cm)
And: 5 + 8 = 13 (cm)
=> The two adjacent sides that make up the angle is equal to each other
So this shape is a quare.
=> This shape is a square.

2. Lin's family has completed 30% of a trip. They have traveled
60 miles. How far is the trip? (Hint: You can use a tape diagram,
Highlight the answer that shows how far Lin's family trip is. (2 points)
Answer:
1. D) 17%
2. 200 miles
Step-by-step explanation:
For the first question we can turn the information into a fraction, with the total number of pieces of fruit in the bowl (12) as the denominator and the number of apples (2) as the numerator.
[tex]\frac{2}{12}[/tex]
Then, divide:
2/12 = 0.17 = 17%
For the second question, we set up a proportion. We know that 60 miles corresponds to 30% and the whole distance of the trip, x, corresponds to 100%
[tex]\frac{60}{x} = \frac{30}{100}[/tex]
Cross multiply and solve:
60 * 100 = 30x
6000 = 30x
200 = x

The measure of <ACD is 120. Find the measure of <ACB, <BCD, and <ACE.
Explain how you found the measure of <ACE.
Answer:
m∠ACB = 39°
m∠BCD = 81°
m∠ACE = 60°
Step-by-step explanation:
From the picture attached,
m∠ACD = 120°
Since, m∠ACD = m∠ACB + m∠BCD
x + (2x + 3) = 120°
3x + 3 = 120
3x = 117
x = 39
Therefore, m∠ACB = 39°
m∠BCD = (2x + 3) = 2(39) + 3
= 81°
Since, m∠ACE + m∠ACB + m∠BCD = 180° [Angles formed at a point on a straight line]
m∠ACE + 39 + 81 = 180
m∠ACE = 180 - 120
m∠ACE = 60°

Could someone help me?
Why does x^4 * x^-4 = 1?
Answer:
Step-by-step explanation:
when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.
You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.
When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.
Does this help?
Answer:
below
Step-by-step explanation:
We can use the product rule of exponents to solve [ x^y * x^z = x^y+z ].
x^4 * x^-4 = 1
x^4+(-4) = 1
x^0 = 1
1 = 1

The lines represented by the equations 20y-24x=-20y and 5y-6x=-5 are
a) perpendicular
b) the same line
c) neither parallel nor perpendicular
d) parallel
Answer:don’t listen to the other guy he’s wrong. The answer is the same line.
Step-by-step explanation:
20y-24x=-20 add 24x to both sides
20y=24x-20
Divide 20 to all
New equation is
Y=5/6x-1
Now let’s solve for 5y-6x=-5
Add 6x to both sides
5y=6x-5
Divide 5 to all
The new equation is
Y=6/5x-1
As you see they have the same equation so the answer is that the lines are the same :) have a good day guys hope this helped <3
in math class, the girl to boy i 8 to 6. if there are 24 girl in the class, how many boy are there?
Answer:
[tex]\huge\boxed{\text{18 boys}}[/tex]
Step-by-step explanation:
This is basically just a ratio. If the ratio between the amount of girls to the amount of boys is 8 to 6, then we can create a fraction (girls/boys)
[tex]\frac{8}{6}[/tex]
Using what we know about the second statement (24 girls) we can make a ratio like this (also assuming girls/boys)
[tex]\frac{24}{x}[/tex]
Since the ratios must be equal, we can set them equal to each other.
[tex]\frac{8}{6} = \frac{24}{x}[/tex]
We can cross multiply to find x.
[tex]24 \cdot 6 = 144\\\\144 \div 8 = 18[/tex]
So there are 18 boys.
Hope this helped!

How do you describe the principal square root of the 34? *
A. The square root of 34 is a rational number.
B. The square root of 34 is an irrational number.
C. The square root of 34 is not defined.
D. The square root of 34 can be a positive or negative number.
Answer:
B. The square root of 34 is an irrational number.
Step-by-step explanation:
The square root of 34 is a rational number if 34 is a perfect square.
Since 34 is not a perfect square, it is an irrational number.
Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number: Option B is correct.
Irrational numbers are numbers that cannot be written as a ratio of two integers.
Examples of irrational numbers are surd functions, euler's number, pi value.Most terminated decimals are also irrational numbers.Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number.
