zero
one
two
infinitely many
Answer:
its b lol
Step-by-step explanation:
jus got it right
There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We have a linear equation in one-variable:
0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)
0.75(x + 40) = 0.7(x + 20)
75(x + 40) = 70(x + 20)
75x = 70x - 1600
x = -370
Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

how do i solve this problem?
12 = 7 - 3x + 5x
Answer: 12=7−3x+5x
Step 1: Simplify both sides of the equation.
12=7−3x+5x
12=7+−3x+5x
12=(−3x+5x)+(7)(Combine Like Terms)
12=2x+7
12=2x+7
Step 2: Flip the equation.
2x+7=12
Step 3: Subtract 7 from both sides.
2x+7−7=12−7
2x=5
Step 4: Divide both sides by 2.

Jenna saves $2,500 per year in an account that earns 10% interest per year, compounded annually. Jenna will have(A $411,234) (B $425,352) (C $449,739) saved in 30 years. Her account balance is a result of Jenna’s(A annuity payments)(B lump-sum payment) .
Answer:
The answer is $43623.50Step-by-step explanation:
This problem is on compound interest.
the expression for compound interest is given as
A=P(1+r)^t
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Given data
P= $2,500
r= 10/100= 0.1
t= 30 years
substituting into the expression for compound interest and solving for A we have
A=2500(1+0.1)^30
A=2500(1.1)^30
A=2500*17.449
A=$43623.50
The final amount is $43623.50
Her account balance is a result of Jenna’s(A annuity payments)

A shop sells matching hats and scarves.The scarves cost 1.5 times as much as the hats.Write two patterns that could represent the cost of 1234 and 5 hats and scarves.List the first 5terms of each pattern.Then explain how to find the cost of 6hats and scarves,using the patterns you wrote u
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Let Cost of hats = h
Cost of scarves = 1.5h
Hence if hats cost $h, then the cost of scarves will be; (1.5 * h)
Using tables :
If the cost of an hat = $2
Hence,
N _____cost of hat(h) ____cost of scarve
1_______2*1 = 2 _________1.5(2) = 3
2______2 *2 = 4 _________1.5(4) = 6
3______2*3 = 6 _________1.5(6) = 9
4 ______ 2*4 = 8 ________1.5(8) = 12
5 ______2 *5=10 ________1.5(10) = 15
Cost of 6 hats and scarve:
Cost of hat:
2 * 6 = $12
1.5h = 1.5(12) = $18

-16x = - 352 step equations
Answer:
x = 22Step-by-step explanation:
-16x = - 352 divide by -16 both sides
x = -352/-16
x = 22
Answer:−16x=−352
Divide both sides by −16.
x= −352/−16
Divide −352 by −16 to get 22.
x=22

Answer:
YZ = 25.40 correct to 1dp
Step-by-Step explanation:
Sin16°= XZ/YZ
YZ=XZ/sin16°
YZ=7/0.276
YZ=25.3623188405797
YZ = 25.40 correct to 1dp
Answer:
XZ ≈ 24.39
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan16° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{YZ}[/tex] = [tex]\frac{7}{YZ}[/tex] ( multiply both sides by YZ )
YZ × tan16° = 7
YZ × 0.287 = 7 ( divide both sides by 0.287 )
YZ = [tex]\frac{7}{0.287}[/tex] ≈ 24.39 ( to 2 dec. places )
2 intersecting lines are shown. A line with point T, R, W intersects a line with points S, R, V at point R. Clockwise, from the top left, the angles are (2 x + 10) degrees, blank, blank, (x minus 10) degrees. What is the measure of angle TRV? 20° 50° 60° 130°2 intersecting lines are shown. A line with points M, H, K intersects a line with points J, H, L at point H. 4 angles are created. Clockwise, from the top, the angles are blank, (x + 15) degrees, blank, (2 x minus 20) degrees. What is mAngleMHJ? 35° 50° 72.5° 92.5°
Answer:
Step-by-step explanation:
a) sum of angle on the straight line TRW is 180.
Given <TRS = 2x+10
<SRW = x-10
<TRS+<SRW = 180
2x+10+x-10 = 180
3x = 180
x = 180/3
x = 60°
<TRV = 180°-(2x+10)
Substitute x = 60° into the expression
<TRV = 180-(2(60)+10)
<TRV = 180-(120+10)
<TRV = 180-130
<TRV = 50°
2) From the diagram attached <MHJ= <LHK (oppositely directed angle)
Given
<MHJ= x+15
<LHK = 2x-20
Substitute the given data into the formula to get x
x+15= 2x-20
x-2x = -15-20
-x = -35
x = 35°
Next is to get the measure of <MHJ
<MHJ = x+15
<MHJ = 35+15
<MHJ = 50°
