help to solve -7 - 3a = 1 - 4a
Answer:
-7 - 3a = 1 – 4a
Step one: Add 4a to -3a
-7 + a = 1
Step two: Add 7 to 1
A = 8
You're done! A=8 for this problem!
Hopefully this helps! Feel free to mark brainliest!
Answer:
[tex]a =8[/tex]
Step-by-step explanation:
[tex]-7 - 3a = 1 - 4a[/tex]
add [tex]3a[/tex] to both sides
[tex]-7 - 3a + 3a = 1 -4a + 3a \\-7 = 1 -a[/tex]
add [tex]-1[/tex] to both sides
[tex]-7 - 1 = 1 - a -1\\-8 = -a[/tex]
multiply both sides by [tex]-1[/tex]
[tex]-8 * (-1) = -a * (-1) \\8 = a[/tex]
Which pair of angles are complementary but not adjacent?
Answer:
1 and 3
Step-by-step explanation:
because 5 and 3 have the same value and since 5 and 1 add up to 90 degrees, 3 and 1 must also add up to 90 degree
Angles ∠1 and ∠3 are complementary but not adjacent.
Complementary angles are two angles that add up to 90 degrees.
Adjacent angles are two angles that share a common vertex and a common side.
In the image, angles ∠1 and ∠3 share a common vertex, but they do not share a common side. They are also not adjacent to each other, as there is an angle in between them (angle ∠4).
The measure of angle ∠1 is 48 degrees. The measure of angle ∠3 is 42 degrees. Therefore, angles ∠1 and ∠3 add up to 90 degrees, making them complementary angles.

$18
4
$36
6
$54

$72
Which describes the relationship between the number of tickets sold and the profit?
Answer:
This is pretty simple, it tells you that two tickets are worth $18, to figure out how much one would cost you just divide 18/2 and that would equal $9. So Your answer would be Each ticket sold yields $9 of profit.
Here, Let, Number of Ticket = x
Sold profit = y
Then, relation would be: 18/2 = 9
y = 9x
In short, Your Answer would be Option B) "Each ticket sold yields $9 of profit"

How many three-digit numbers are multiples of neither 5 nor 7?
Answer:
590Step-by-step explanation:
Total 3-digit numbers 100 to 999
999 - 99 = 9003 digit multiples of 5; 100 to 995
smallest one 100 = 5*20greatest one 995 = 199*5number 199 - 4 = 1953 digit multiples of 7:
smallest one 105/7 = 15greatest one 994/7 = 142number 142 - 14 = 128Total multiples of either 5 or 7 :
195 + 128 = 323This number includes multiples of both 5 and 7
We need to exclude half of the multiples of 5*7= 35 as they are counted twice:
smallest one 105 = 35*3greatest one 980 = 28*35number 28 - 2 = 26Half of this is 26/13 = 13
323 - 13 = 310The difference of 900 and 310 is the answer:
900 - 310 = 590An equation of a line with a slope of - 4/5 that passes through the point (5,3)
Answer:
y = -(4/5)x + 7
Step-by-step explanation:
recall that the point-slope form of a linear equation is given as
y - y₁ = m (x - x₁)
in our case, we are given
slope, m = -4/5
and a point (x₁, y₁) = (5,3)
hence we simply substitute these values into the equation
y - y₁ = m (x - x₁)
y - 3 = -(4/5) (x - 5) (we will simplify this to convert to slope-intercept form)
y - 3 = -(4/5) (x) - (-4/5)(5)
y - 3 = -(4/5)x +4 (add 3 to both sides)
y = -(4/5)x +4 +3
y = -(4/5)x + 7

Rhonda had $300 to buy supplies for the animal shelter. She bought 8 bags of dog food and 11 leashes. Each bag of food cost $25.19, and each leash cost $4.65.
How much money did Rhonda have left after her purchases?
A. $11.65
B. $14.29
C. $22.91
D. $47.33
Answer:
47.33
Step-by-step explanation:
Hey there! I'm happy to help!
We have 8 bags of dog food and each costs $25.19
8(25.19)=201.52
And we have 11 leashes each costing $4.65.
11(4.65)=51.15
We add these totals up.
201.52+51.15=252.67
We subtract this from 300 to see how much is left.
300-252.67=47.33
Rhonda had $47.33 left after her purchases.

In order to test for the significance of a regression model involving 14 independent variables and 255 observations, the numerator and denominator degrees of freedom for the critical value of the fare is:___________.
A. 14 and 255
B. 255 and 14
C. 13 and 240
D. 14 and 240
Answer:
C; 13 and 240
Step-by-step explanation:
Here in this question, we are to give the numerator and the denominator degrees of freedom.
Mathematically;
the numerator degrees of freedom = number of variables - 1 = 14 -1 = 13
The numerator degrees of freedom = number of observations- numerator degrees of freedom - 1
= 255 - 14-1 = 255-15 = 240
The critical value of the fare is options c. 13 and 240.
Calculation of the critical value:Since the numerator degrees of freedom should be
= number of variables - 1
= 14 -1
= 13
Now
The numerator degrees of freedom should be
= number of observations- numerator degrees of freedom - 1
= 255 - 14-1
= 255-15
= 240
Therefore, the correct option is c.

What is the ratio of enlargement to the original? Convert the ratio to a percent.
Answer/Step-by-step explanation:
The ratio of the enlargement to the original = A'E' to AE = A'E':AE = A'E'/AE
AE = 2.5
A'E' = 4
Ratio of the enlargement to the original = 4:2.5 = 1.6:1
To convert to percentage, divide 4 by 2.5 and multiply by 100.

Given
P ( W ) = .72 , P ( D ) = .3
P ( W∩D ) = .2
a )
P ( [tex]W^c[/tex] ∩ [tex]D^c[/tex] ) = P[tex]( WUD)^c[/tex] = 1 - P ( W U D )
= 1 - [ P( W ) + P ( D ) - P ( W ∩ D ) ]
= 1 - ( .72 + .3 - .2 ) = .18
b )
P ( D / W ) = P ( W∩D ) / P(W) = .2 / .72 = .27778
c )
No , because
P ( W∩D ) = .2
p ( W) x P ( D ) = .72 x .3 = .216
so P ( W∩D ) is not equal to P ( W) x P ( D )
