Answer:
The solution to the system of equations are;
x = -4/3
y = 5/3
Step-by-step explanation:
To find the Solution, we would carry the Operation simultaneously.
4x + 2 = -2y .........(i)
6y - 18 = 6x ..........(ii)
First let's rearrange the equations, to make the journey smoother
2y + 4x = -2 ...........(iii)
6y - 6x = 18 ...........(iv)
Let's Multiply equation (III) by 3 so as to have a uniform spot to begin elimination.
3.2y + 3.4x = -2 . 3
6y + 12x = -6............... (v)
Let's subtract equation (v) from equation (iv)
= 0y - 18x = 24
-18x = 24
x = - 24 / 18
x = -4/3
Let's substitute (x = -4/3) in equation (ii), so that we can solve for the value of y:
6y - 18 = 6x
6y - 18 = 6 (-4/3)
6y - 18 = -8
6y = -8 + 18
6y = 10.
y = 10 / 6
y = 5/3
The solution to the system of equations are;
x = -4/3
y = 5/3
Answer:
Her first coupon ti be used is $50 off a purchase above $300
Final purchase price= $340
Step-by-step explanation:
Marie has two coupons
one for a 15% discount and one for $50 off any purchase above $300.
The stores allow the two coupons to be combined and she spends a total of $450.
Her first coupon ti be used is $50 off a purchase above $300.
So Marie have $400 now
15% off $400= 400-(0.15*400)
15% off $400 = 400-60
15% off $400 =$ 340
<u>Answer:</u>
- The value of ∠TMV is 45°.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- ∠VTM + ∠TMV + ∠MVT = 180°
- ∠VTM = 92
- ∠MVT = 43
<u>Work:</u>
- ∠VTM + ∠TMV + ∠MVT = 180°
- => 92 + 43 + ∠TMV = 180°
- => 135 + ∠TMV = 180°
- => ∠TMV = 180 - 135
- => ∠TMV = 45°
Hence, <u>the value of ∠TMV is 45°.</u>
Hoped this helped.
