if 1/4x +2y= 11/4
and - 6y - x = 7, what is
half of y?
Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ -x - 6y = 7
2y = 18
y = 9
half of 9 = 4 1/2
- Drake and troy are building models. For every 10 pieces
Drake puts together, Troy puts together 6 pieces. If Troy
puts together 18 pieces, how many pieces does Drake
put together?
Answer:
30
Step-by-step explanation:
Looking at the question we will notice that every 6 that Troy puts together Drake makes 10 so its simple, Troy makes 18 so we divide that by 6 meaning we get 3. We then get 3 and multiply it by 10, Thus 30 shall be our answer.

millicent earned $435 last year in interest. If $3000 was invested at a certain rate of return and $4500 was invested in a fund with a rate that was %2 lower, find the 2 rates of interest
Answer:
7% and 5%
Step-by-step explanation:
The computation of the two rates of interest is shown below;
The interest rate for $3,000 be x%
And, for $4,500 the interest rate is (x -2%)
The total interest earned is
= x% of $4,500 + (x - 2)% of $4,500
So, the two rates of interest is
x% of $4,500 + (x - 2)% of $4,500 = $435
30x + 45(x - 2) = $435
30x + 45x - 90 = $43
75x = $25
x = 7%
x - 2 = 7 - 2
= 5%
What is an equation of the line that passes through the points
(6,1) and (7,2)? Put your answer in fully reduced form.
Answer (assuming it can be in slope-intercept form):
y = x - 5
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the x and y values of the given points into it. Then, solve:
[tex]m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1[/tex]
2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or [tex]y-y_1 = m (x-x_1)[/tex]. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.
[tex]y-1 = 1(x-6)\\y -1 = x-6\\y = x -5[/tex]

3x - 2 = x + 10
X+4=19-2x
8z - 20 =z +15
Answer:
1st answer is 6, 2nd is 5, 3rd is 5
Step-by-step explanation:
3x-2=x+10
3x-x=10+2
2x=12
x=12÷2
x=6
x+4=19-2x
x+2x=19-4
3x=15
x=15÷3
x=5
8z-20=z+15
8z-z=15+20
7z=35
z=35÷7
z=5
plzz mark me as brainliest
Answer:
3x-2=x+10
x=6
x+4=19-2x
x=5
8z-20=z+15
z=5
Step-by-step explanation:
3x-2=x+10
+2 on both sides
3x-2(+2)=x+10(+2) => 3x=x+12
subtract x on both sides
3x(-x)=x(-x)+12 => 2x=12
divide 2 on both sides
2x/2=12/2
= x=6
x+4=19-2x
subtract 4 on both sides
x+4(-4)=19(-4)-2x => x=15-2x
add 2x on both sides
x(+2x)=15-2x(+2x) => 3x=15
divide 3 on both sides
3x/3=15/3
= x=5
8z-20=z+15
subtract z on both sides
8z(-z)-20=z(-z)+15 => 7z-20=15
add 20 on both sides
7z-20(+20)=15(+20)
7z=35
divide 7 on both sides
7z/7=35/7
= z=5

What value is equivalent to (5-3•2^3) + 9-4^2? PLS HURRYYY
Answer:
-26 is your answer
Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.

shown is a regular pentagon, find y.
Answer:
54 degrees
Step-by-step explanation:
Every side of a regular pentagon is same.
So we have an isosceles triangle. The correspond angle of y, must equal to y (degree) too.
Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.
y=54

∠1 and ∠2 are complementary angles. If ∠1 measures 35º, what is the measure of ∠2?
Answer:
55 degrees
Step-by-step explanation:
Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees
90=35+∠2
-35 -35
55=∠2
Find the common solution.
x = - y + 10
x = y + 4
Type answer as an ordered pair.
Answer:
Step-by-step explanation:
x = -y + 10
Substitute into the second equation
-y + 10 = y + 4
-2y = -6
y = 3
Plug into first or second equation.
x = -3 + 10 = 7
x = 3 + 4 = 7
So the ordered pair is (7,3)

What is the answer for this eqation? 20-3x=9-7x
Answer:
x = - 11/4
Step-by-step explanation:
20- 3x = 9 - 7x
Add 7x to both sides
20 - 3x + 7x = 9 - 7x + 7x
20 + 4x = 9
Now,Subtract 20 from both sides
20 -20 + 4x = 9 - 20
4x = -11 {Divide both sides b 4}
x = -11/4
Answer:
= -11/4
Step-by-step explanation:
Rearrange terms
−3+20=9−7
− 3 + 20 = − 7 + 9
Subtract 20 from both sides of the equation
− 3 + 20 = − 7 + 9
− 3 + 20 − 20 = − 7 + 9 − 20
Simplify / Subtract the numbers
− 3 = − 7 − 1 1
Add 7 7x 7x to both sides of the equation
− 3 = − 7 − 1 1
− 3 + 7 = − 7 − 1 1 + 7
Simplify / Combine like terms
4 = − 1 1
Divide both sides of the equation by the same term
4 = −11
4/4 = -11/4
Simplify / Cancel terms that are in both the numerator and denominator
= -11/4
Solve the system of equations by using substitution.
