101 = -4 + 5(x + 2)
please help
Answer:x=19
Step-by-step explanation:
101 = -4 + 5(x + 2)
101= -4 +5x+10
91=-4+5x
95=5x
x=19
19
Step-by-step explanation:
Distribute 5
101=-4+5x+10
Combine like terms
101=5x+6
Get x alone on one side by subtracting 6
95=5x
Simplify
19=x
What is a simple way to tell that −2 1/5 is not the slope of this graph?
Answer:
The last one is an easy way to tell that the slope is not -2 1/5 because it is positive
Step-by-step explanation:
When a line goes up from left to right, it's positive. If it goes down from left to right, it's negative.

Which property is illustrated by the equation
3x – 6y = 3(x - 2y)?
1. associative
2.Commutative
3.distributive
4.closure
Answer: 3. Distributive
Step-by-step explanation:
3(x -2y) = 3x - 6y To get from left to rigth, you have to multiply them which is the same as distribitue.
3(x) - 3(2y) = 3x - 6y

Which statement describes how the slope relates to the height of the water in the pool? Height of Water in a Pool Time (min) 2 4 6 8 10 Height (in.) 8. R12 16 20 24 O The height of the water increases 2 inches per minute. The height of the water decreases 2 inches per minute. The height of the water was 2 inches before any water was added. O The height of the water will be 2 inches when the pool is filled.
Answer:
Step-by-step explanation:
Answer:
A) The height of the water increases 2 inches per minute.
Step-by-step explanation:
Slope is the rate of change of height
m = (16 - 12)/(4 - 2) = 4/2 = 2
2 inch per min
Positive slope implies increase
Which expression is equivalent to 3n+2(1-4n)?
A. 2-n
B. 2-5n
C. 2+11n
D. 2-11n
Answer:
The Answer is B. 2-5n
Step-by-step explanation:
Multiply 2 by everything within the parenthesis and it leaves you with 3n+ 2-8n
Then combine like terms which are +3n and -8n which leaves you with -5n

Mix 3 liters of water with 4 lemons to make lemonade. How many liters of water are mixed with 8 lemons how many liters of water will you need to make lemonade?
Answer:
6 Liters
Step-by-step
4 Lemons = 3 Liters
8 Lemons = 6 Liters
So its basicly multiplying it by 2 ^O^
Answer:
X = 6
Step-by-step explanation:
number of lemons. Liters
4 ---> 3
8 ---> X
= 4:8 = 3: X
= 4 = 3
8 X
= 4X = 3×8
= X = 3 × 8

What is the value of x in the equation 5(3x + 4) = 23?
start fraction 43 over 15 end fraction
start fraction three over 15 end fraction
start fraction 15 over 43 end fraction
start fraction two over five end fraction
Answer:
5(3x+4)=23
5*3=15 5*4=20
15x+20=23
-20=-20
15x=3
divide by 15 from both sides
x=0.2
Step-by-step explanation:
Answer:
5(3x+4)=23
5*3=15 5*4=20
15x+20=23
-20=-20
15x=3
divide by 15 from both sides
x=0.2
Explanation: In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates"). As an example, the fraction 8/5
amounts to eight parts, each of which is of the type named "fifth". In terms of division, the numerator corresponds to the dividend, and the denominator corresponds to the divisor.
Informally, the numerator and denominator may be distinguished by placement alone, but in formal contexts they are usually separated by a fraction bar. The fraction bar may be horizontal (as in 1/3), oblique (as in 2/5), or diagonal (as in 4⁄9). These marks are respectively known as the horizontal bar; the virgule, slash (US), or stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions", and diagonal ones as "em" or "mutton fractions", based on whether a fraction with a single-digit numerator and denominator occupies the proportion of a narrow en square, or a wider em square. In traditional typefounding, a piece of type bearing a complete fraction (e.g. 1/2) was known as a "case fraction", while those representing only part of fraction were called "piece fractions".

6) In 3 seconds you can fill up a pool with 42 gallons of water. If this is a proportional
relationship fill in the table below.
Time (sec) 1/2/3/4/5
Amount of /. /42/. /. /
Water (gal)
Answer:
1/2/3/4/5
14/28/42/56/70
Step-by-step explanation:
divide the 42 gallons by 3 (since 3 seconds for 42 gallons) to find the rate of change. the answer is 14. then just do the number times 14 all the way. and yes this is proportional
can someone please help me?
Answer:
70°
Step-by-step explanation:
since two lengths are equal to 3.5 that’s means there’s are two equal angles (55° and 55°)
a triangle adds up to 180°
so to find x we set this up:
x +55 +55 = 180
x + 110 = 180
x = 70°
Based on the graph, which inequality is correct for a number that is to the right of -3?
A number line is shown from negative 8 to 8 at increments of 1. A circle is shown at negative 3. The entire portion of the number line to the right of negative 3 is shaded.
a
4 > −3
b
−3 > 4
c
−2 < −3
d
−3 < −6
Answer:
The inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
Step-by-step explanation:
Given the inequality
[tex]-3\:>\:4[/tex]-3 can not be greater than 4, so [tex]-3\:>\:4[/tex] is also incorrect.
Given the inequality
[tex]-2\:<\:-3[/tex]-2 can not be lesser than -3, so [tex]-2\:<\:-3[/tex] is also incorrect.
Given the inequality
[tex]-3\:<\:-6[/tex]-3 can not be lesser than -6, so [tex]-3\:<\:-6[/tex] is also incorrect.
Given the inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
