SOLVE PLS HURRY PLS INCLUDE STEPS 4a + 1 - a = 19
Answer:
a=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4a+1−a=19
(4a+−a)+(1)=19 (Combine Like Terms)
3a+1=19
Step 2: Subtract 1 from both sides.
3a+1−1=19−1
3a=18
a=18/3
a=6

Please help ASAP Gavin works as a salesperson at an electronics store and sells phones and phone accessories. Gavin earns a $12 commission for every phone he sells and a $3.50 commission for every accessory he sells. On a given day, Gavin made a total of $135 in commission and sold 12 more accessories than phones. Determine the number of phones sold and the number of accessories sold.
There were
____phones sold and
____ accessories sold.
Answer:
6 phones and 18 accessories
Step-by-step explanation:
12P + 3.50A = 135
A = 12 + P
12P + 3.50(12 + P) = 135,
12P + 42 +3.50P = 135
15.50P = 93
P = 6 phones
A = 12 + 6 = 18 accessories

Then 4 times 4 is 16.
I need help with this!
Please help!!!!!
Answer:
96
Step-by-step explanation:
100%-60%=40%
40% of x = 64 students (X=Total no. of students)
(40/100)*x=64
x=64*(100/40)
x=160
Missing no. of students=160-64=96
Answer:
96 students
Pls mark me brainliest!
Step-by-step explanation:
If an unknown amount of students is 60% of the students, the 64 of the students must be 40% of the students because 40+60 = 100.
You want to find what 1% equals, so we will divide 64 by 40 because 40% divided by 40 = 1% and whatever you do to one side you do to the other.
64/40 = 1.6
Assuming that the ? number of students that equals 60% will be a whole number, lets go with 1.6.
If 1.6 = 1%, and we want 60%, then multiply both sides by 60, because 1*60 = 60.
1.6*60 = 96

Find the domain of the graphed function
Answer:
D. 2 ≤ x ≤ 5
Step-by-step explanation:
Notice that there are no points on the graph for x ≤ 2 and x ≥ 5. Or another way to look at it is that the x's are between 2 and 5, inclusive.
The domain is the set of possible x values. Therefore, 2 ≤ x ≤ 5 is the set of values for the domain

Anyone know the answer to this question?
9514 1404 393
Answer:
140°
Step-by-step explanation:
The value of the exterior angle (x°) is the sum of the other two angles shown. These are known as "remote interior angles."
x° = 64° +76°
x° = 140°
_____
Additional comment
This relationship derives from the fact that the exterior angle and the adjacent interior angle have a sum of 180° (they are a linear pair). We also know that the adjacent interior angle and the other two given angles have a sum of 180°.
If we call the unknown interior angle U, these relations are ...
64 + 76 + U = 180 . . . . sum of angles in a triangle
x + U = 180 . . . . . . . . . . sum of angles in a linear pair
Comparing these two equations, we see that ...
64 + 76 = x

28. Construct a rectangle ABCD in which AB = 4 cm, BC = 3.5 cm. Construct a triangle whose area is equal to that of rectangle ABCD
Answer:
Triangle b = 4, h = 7
Step-by-step explanation:
Rectangle area = L*W
Triangle area = (B*H)/2
Rectangle/2 = Triangle
If you want triangle to = rectangle, then rectangle*2/2
Rectangle = 4*3.5 = 14
Triangle = 4*7 = 28/2 = 14

Answer:
x= 1 , y=4
Step-by-step explanation:
x-y= -3 => Equation 1
x+5y= 21 => Equation 2
Substitution Method:
Substitute Equation 1=>
x=y-3 <= Equation 3
Put x=y-3 in Equation 2:
x+5y=21
( y-3)+5y=21
y-3+5y=21
6y-3=21
6y=21+3
6y=24
y=24÷6
y=4
Put y=4 in Equation 1:
x-y= -3
x-4=-3
x=4-3
x=1
Hope this helps :)
Answer:
x = 1
y = 4
Step-by-step explanation:
x - y = -3 then x = y - 3
x + 5y = 21
substitute for x:
y - 3 + 5y = 21
reduce:
6y = 24
y = 4
x = 4 - 3 = 1
check:
1 - 4 = -3
-3 = -3
and
1 + 5(4) = 21
21 = 21

Find the values of x and y. y=? x=? PLEASE HELP
Answer:
x=15.714
y=5.715
Step-by-step explanation:
Answer:
x=10, y=20
Step-by-step explanation:
okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20
so 90+20+7x=180
and:110+7x=180
therefore: 7x=70
and finally: x=10
To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:
5x+2y=90
and we know x=10
so 5x=50
meaning that: 50+2y=90
therefore: 2y=40
and in conclusion y=20

Answer:
2x -1
Step-by-step explanation:
The perimeter is the sum of the side lengths.
P = 6 + (x -4) + (x -3)
P = 2x -1 . . . . . . collect terms
The perimeter is 2x -1.

There is nothing in the problem statement that suggests this is a right triangle. Without knowing at least one angle, we cannot solve for a numerical value for the perimeter. The problem title suggests we're to leave the result in polynomial form.
