Answer:
(6,2)
Step by Step explanation:
1- Add the two equations so the Xs cancel out
2- find y by dividing 6 from both sides
3- plug in the y value in the place of the y in one of the equations
4- solve the equation to find X
5 - put answer in correct format (x,y)
Angle Q and angle S equal 61
Steps to solve for the zero:
(x + 7)(x + 5) = 0
~Set both factors to equal zero
x + 7 = 0
x + 5 = 0
~Solve for x in [ x + 7 = 0 ]
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
~Solve for x in [ x + 5 = 0 ]
x + 5 = 0
x + 5 - 5 = 0 - 5
x = -5
Therefore, the solutions are x = -7 and x = -5
Best of Luck!
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411
Answer:
72
Step-by-step explanation:
To calculate how much 20% of 360 makes we multiply 360 with 20 then divide it with 100
360 × 20 ÷ 100 = 72
