Answer:
x=24
Step-by-step explanation:
Hello There!
Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180
So we setup an equation
180=2x+12+5x
step 1 combine like terms
5x+2x=7x
now we have
180=7x+12
step 2 subtract 12 from each side
12-12 cancels out
180-12=168
now we have
168=7x
step 3 divide each side by 7
7x/7=x
168/7=24
we're left with~ x=24

Ken bought 2 video games and 1 DVD for a total of $105. Jerome bought 1 video game and 4 DVDs for a total of $80. Which system of equations can be
used to find the cost, in dollars, of each video game (v) and each DVD (d) at the store?
Answers
Answer:
I think that the Linear system of equations can be used to find the cost.
Step-by-step explanation:
Answer:
2v + 1d = 105
and
1v + 4d = 80
Step-by-step explanation:
ken : 2v + 1d = 105
Jerome : 1v + 4d = 80
1v + 4d = 80 Try to get a video games by its self
- 4d -4d
1v = 80 - 4d
Plug into kens equation..
2(80 -4d) + 1d = 105
160 - 8d + 1d = 105
-160 -160
-7d = -55
/-7 /-7
d = 7.86 (rounded)
Plug into Jeromes equation
1(7.86) + 4v = 80
- 7.86 - 7.86
4v = 72.14
/4 /4
v = 18.035 (round = 18)
Melanie is going to invest in an account paying an interest rate of 5.2% compounded
monthly. How much would Melanie need to invest, to the nearest hundred dollars,
for the value of the account to reach $19,600 in 19 years?
Answers
Answer:
7300
Step-by-step explanation:
I got it right
Melanie would need to invest an amount of $7300.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
The final amount in a compound interest can be calculated using the formula,
A = P (1 + [tex]\frac{r}{n}[/tex] )^(n t)
Here A is the final amount, P is the principal value, r is the rate of interest, n is the number of times interest is compounded per year and t is the number of years.
Given,
A = $19,600
r = 5.2% = 5.2/100 = 0.052
Since it is compounded monthly, n = 12
t = 19 years
Substituting,
19,600 = P (1 + [tex]\frac{0.052}{12}[/tex])^ (12 × 19)
19,600 = P (1.0043)^(228)
19,600 = P (2.68)
P = 19,600 / 2.68
P = 7313.0767 ≈ 7300 to the nearest hundred
Hence the value of the account will reach $19,600 n 19 years if she invest an amount of $7300.

What is m∠A and what is m∠B?
Answers
Answer:
m∠A = 79°m∠B = 112°Step-by-step explanation:
We have cyclic quadrilateral as all vertexes are on the circle.
As per property of cyclic quadrilateral, each pair of opposite angles are supplementary.
As we know supplementary angles add up to 180°.
m∠A + m∠C = 180° ⇒ m∠A = 180° - 101° = 79°m∠B + m∠D = 180° ⇒m∠B = 180° - 68° = 112°8.sınıf matamatikten hic anlamıyorum yardım edin

The area is 2,600 cm^2
Step-by-step explanation:
The area of a rectangle is the product of its sides
And the difference between both areas is 1,400 cm^2 (P-Q)
Thus, we have it that;
40(3x-10) - (30(x + 15)) = 1,400
120x - 400 - 30x - 450 = 1400
120x -30x -400-450 = 1400
90x - 850 = 1400
90x = 1400 + 850
90x = 2,250
x = 2,250/90
x = 25
The area for painting P
is;
40 (3x - 10)
Substituting the value 25 for x
we have
40 ( 3(25) -10)
= 40(75-10)
40 * 65 = 2,600 cm^2
