7(m+5) = 21
What is it?
Answers
Answer:
m = -2
Step-by-step explanation:
Look at the attached image. First, we divide both sides by 7 to get m + 5 = 3. Now, we subtract 5 from both sides to get m = -2. Now, we substitute m for -2. As we can see, it checks out.
The solution of expression is,
m = - 2
We have to give that,
An expression to solve,
7 (m + 5) = 21
Now, simplify the expression as,
7 (m + 5) = 21
Divide both sides by 7,
m + 5 = 21 / 7
m + 5 = 3
Subtract 5 both side,
m = 3 - 5
m = - 2
So, The solution is, m = - 2

Answer:
We have a slope and a point, this way, we do not need to find the slope using two points. We can find the line using the Slope Form to turn it into Slope-Intercept Form, also known as "y = mx + b". We can use the Slope Form which is "y - y1 = m(x - x1)". A coordinate is "(x,y)", so that means, "(-1,4)" means that x = -1 and y = 4. We can substitute y1 for 4 and x1 for -1, and m for -5 since m is the slope. Plugging that information into the Slope Form Formula we get "y - 4 = -5(x - (-1))". We know that a negative with a negative turn positive, so we can use this information to change the formula to "y - 4 = -5(x + 1)". Now we distribute and simplify, these steps are shown below.
y - 4 = -5(x + 1)
y - 4 = -5x -5
y - 4 + 4 = -5x - 5 + 4
y = -5x - 1
Now that we have simplified it, we can see that the slope is -5 and the -1 is the y-intercept. To check this is a linear equation is to graph it, or substitute three x-coordinate or y-coordinates and draw a line. In conclusion, the equations is y = -5x - 1.

Step-by-step explanation:
Question: the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with.
If the chess club accepts 5 each week and they had 6 members after 6 weeks you should multiply 5x6=30. We don't know when the chess club started.. it could be 6 or 7 weeks ago and I'm pretty sure we all know that 7x5=35. but it only says 6 weeks ago so the answer is 7,

Can yall find EB? Round the the nearest hundred. AD=8.98, AB=6.47. ABCD is a rectangle
Answers
Answer:
5.53408980773 or 5.534
Step-by-step explanation:
Let's take AD as a, AB as b and DB as c
a2+b2 =c2
(8.98)2 + (6.47) 2 =c2
80.6404 + 41.8609 =c2
The number 2 is square . take it like square
122.5049 =c2
[tex] \sqrt{c \: \: } = \sqrt{122.5049 } [/tex]
C=11.0681796155
this valse is DB but the question say EB so dividend by 2 because rectangle diagonal are equal
So EB =11.0681796155/2
EB =5.5340890773

A forest covers 68,000 acres. A survey finds that 0.8% of the forest is old-growth trees. How many acres of old-growth trees are there?
Answers
Answer:
544 acres
Step-by-step explanation:
There is 100% in a whole.
1% is 1/100th of the whole, or 0.01 of it. We get this because 1/100 = 1/100 = 0.01
Similarly, 0.8/100 = 0.008. We then multiply the decimal by the total to get
(0.008) ( 68000) = 544 acres

1 AB
2 BC
Answers
Answer:
AB ≈ 15.7 cm, BC ≈ 18.7 cm
Step-by-step explanation:
(1)
Using the Cosine rule in Δ ABD
AB² = 12.4² + 16.5² - (2 × 12.4 × 16.5 × cos64° )
= 153.76 + 272.25 - (409.2 cos64° )
= 426.01 - 179.38
= 246.63 ( take the square root of both sides )
AB = [tex]\sqrt{246.63}[/tex] ≈ 15.7 cm ( to 1 dec. place )
(2)
Calculate ∠ BCD in Δ BCD
∠ BCD = 180° - (53 + 95)° ← angle sum in triangle
∠ BCD = 180° - 148° = 32°
Using the Sine rule in Δ BCD
[tex]\frac{BC}{sin53}[/tex] = [tex]\frac{BD}{sin32}[/tex] = [tex]\frac{12.4}{sin32}[/tex] ( cross- multiply )
BC × sin32° = 12.4 × sin53° ( divide both sides by sin32° )
BC = [tex]\frac{12.4sin53}{sin32}[/tex] ≈ 18.7 cm ( to 1 dec. place )

square root of 9 multiplied by square root of 180
Answers
Answer:
18√5
Step-by-step explanation:
√9×√180
from √9 we get 3 cause 3² is 9.
from 180 we get 6√5 because √36×5 is √180.
we took 36 out because it gives us a whole number if we square root it.
So √36×5 is 6√5 , because the square root of 36 is 6
then we multiply 3 and 6√5.
3×6 is 18 so we put 18 and put the √5 behind it.
Find the sum of the squares of 3, 2, 1, and -1

3 x 3=9
2 x 2=4
1x1=1
-1x-1=1
9+4+1+1=15
Answer:
15
Step-by-step explanation:
The square of 3 is 3 times 3, so 9.
2 times 2 is 4.
1 times 1 is 1.
-1 times -1 is 1, because the negative cancels out.
So, it's 9 plus 4 plus 1 plus 1, so the answer is 15.
