Answer:
[tex]b=0.8[/tex]
Step-by-step explanation:
1) Subtract 2.7 from both sides.
[tex]-5.3-2.7=-\frac{b}{0.1}[/tex]
2) Simplify -5.3 - 2.7 to 8.
[tex]-8=-\frac{b}{0.1}[/tex]
3) Multiply both sides by 0.1.
[tex]-8[/tex] × [tex]0.1=-b[/tex]
4) Simplify - 8 × 0.1 to - 0.8.
[tex]-0.8=-b[/tex]
5) Multiply both sides by -1.
[tex]0.8=b[/tex]
6) Switch sides.
[tex]b=0.8[/tex]
Answer:
b=0.8
Step-by-step explanation:
[tex]\frac{b}{0.1} = 8\\b= (0.1)(8)\\b=0.8[/tex]

Harita must memorize 90 measures of music for her cello solo at a concert. She plans on memorizing 18 new measures for every 3 days of practice. Which equation can be used to determine m, the number of measures Harita still needs to memorize, as a function of d, the number of days of practice since she began learning the piece?
m = 72 – 15d
m = 90 – 6d
m = 101 – 21d
m = 108 – 3d
Answer:
m = -90 - 6d
Step-by-step explanation:
18 ÷ 3 = 6 { She needs to memorize six measures a day. }
m = 90 - 6d { She has memorized bd measures }

please brainliest
solve 4n - 8 = 14n + 12
please help <3 ( will give brainliest )
Basically...
4n - 8 = 14n + 12
Simply collect like terms,
4n-14n=12+8
-10n=20
Divide both sides by -10
n= -2
Please mark BRAINLIEST.
Step-by-step explanation:
[tex]4n - 8 = 14n - 4n \ \\ - 8 - 4 = 14n - 4n \\ - 20 = 10n \\ - \frac{20}{10} = n \\ n = - 2[/tex]

What is the y-intercept of the equation 2x + 4y = -16?
1. -16
2. -8
3. -4
4. -2
Answer:
3) -4
Step-by-step explanation:
Hi there!
2x + 4y = -16
The y-intercept occurs when x=0. Replace x with 0 and solve for y:
2(0) + 4y = -16
4y = -16
y = -4
Therefore, the y-intercept is -4.
I hope this helps!

Use the graph to estimate the value of y when x=2.5
Answer:
I'm guessing: The value of y is 6.5
Step-by-step explanation:
Mark 2.5 on the x-axis between 2 and 3, then draw a line to meet the graph.
Or use the table , y=3x-1
y=3(2.5)-1
y=7.5-1
y=6.5

[tex]A(4,5) and B (3,4)\\[/tex]Find distance betweentwo points A(4,5) and B (3,4)
Answer:
√2
Step-by-step explanation:
given points are,
A = (4,5)
B = (3,4)
we know,
D = √(x_2 - x_1)² + (y_2 - y_1)²
→ √(3-4)² + (4-5)²
→ √(-1)² + (-1)²
→ √1 + 1
→ √2
therefore, distance between A and B is √2.
hope this answer helps you dear...take care and may u have a great day ahead!

Find the slope of the line
(15,18) (6,12)
Answer:
slope = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (15, 18 ) and (x₂, y₂ ) = (6, 12 )
m = [tex]\frac{12-18}{6-15}[/tex] = [tex]\frac{-6}{-9}[/tex] = [tex]\frac{2}{3}[/tex]
Remember, when finding the slope, use this formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex]
We can start by labeling (15, 18) as [tex]x_{1}[/tex] and [tex]y_{1}[/tex] and (6, 12) as [tex]x_{2}[/tex] and [tex]y_{2}[/tex]. Now, we can plug these number into the formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }=\frac{12-18}{6-15}=\frac{-6}{-9} =\frac{2}{3}[/tex]
Thus, the slope of the line is [tex]\frac{2}{3}[/tex]. Hope this helps! Let me know if you have any questions related to this problem.

Bill and Ben each have three cards, numbered 1, 2 and 3. They each take one of their own cards. Then they multiply together the two numbers on the cards. a) What is the probability that their answer is an even number? b) What is the probability that their answer is a number greater than 5?
The probabilities are given as follows:
a) Even number: 5/9.
b) Number greater than five: 1/3.
What are probabilities?A probability is the division of the number of desired outcomes by the number of total outcomes.
Given that each person draws one card from a set of three, hence the total number of outcomes is given as follows:
3² = 9.
Using the Fundamental Counting Principle,
The nine outcomes are given as follows:
1 x 1 = 1.
1 x 2 = 2.
1 x 3 = 3.
2 x 1 = 2.
2 x 2 = 4.
2 x 3 = 6.
3 x 1 = 3.
3 x 2 = 6.
3 x 3 = 9.
There are five outcomes that end with an even number, hence the probability is of:
p = 5/9.
There are three outcomes ending with a number greater than five, hence the probability is of:
p = 3/9 = 1/3.

explain how you got the answer because I somehow got x > -5 as my answer, please and thanks.
Answer: x>-5
Step-by-step explanation:
-5(x+7)<-10
Distribute the -5.
-5x-35<-10
Add 35 to both sides.
-5x<25
Divide both sides by -5.
x>-5
Answer:
x > - 5
Step-by-step explanation:
-5(x+7)< -10
-5x - 35 < - 10
- 5x < - 10 + 35
x > 25/-5
