Answer:
Step-by-step explanation:
Answer: x = 7 and y = -2
Step-by-step explanation:
2x +3y = 8 ----------------(1)
x-y = 9 ----------------------(2)
multiply (2) by 2
2x-2y = 18--------------------(3)
subtract (2) from (3)
-5y = 10
Divide bothside by -5
y = -2
Similarly, multiply (2) by 3
3x-3y = 27-----------------------(4)
add (1) and (4) together
5x = 35
Divide bothside by 5
x= 7
Therefore, x =7 and y= -2
Answer:
1845 cm
Step-by-step explanation:
The formula of triangle is 1/2(b)(h)
B is the height and A is the base.
90 times 41 divided by 2
Answer: 510 flights
Step-by-step explanation:
85% are expected to arrive on time, so we can convert that to a decimal, which is 0.85. (To convert a percentage to a decimal we can divide by 100.)
After this we take the TOTAL AMOUNT OF FLIGHTS x 0.85
Total Amount = 600
600 x 0.85 = 510.
Answer:
hello : y = 3x² -24x +26 ......answer: C
Step-by-step explanation:
y = 3(x-4)² -22
by idetity : (x-4)² = x²- 8x+16
y = 3(x²- 8x+16 ) -22
y = 3x² - 24x +48 -22
y = 3x² -24x +26 ......answer: C
