Answer:
(11, 13)
Step-by-step explanation:
First Equation: x+y=24
Second Equation: y=x+2
x + (x + 2) = 24
2x + 2 - 2 = 24 - 2
2x/2 = 22/2
x = 11
y = (11) + 2
y = 13
Therefore, the solution to the system is (11, 13)
1.5 x 2 = 3 So you do 2.4 x 2 = 4.8 and the answer is 4.8 miles
Answer:
try A,C and E because A) has more students than any other ones C) if I goes up in twos and E) same as C
Answer:
x = 3
y = 2
Step-by-step explanation:
4x + 3(3x - 7) = 18 <em>Substitute</em><em> </em><em>y</em>
4x + 9x - 21 = 18 <em>Simply</em>
13x - 21 = 18 <em>Add</em><em> </em><em>like</em><em> </em><em>terms</em>
13x = 39 <em>Add</em><em> </em><em>2</em><em>1</em>
x = 3 <em>Divide</em><em> </em><em>by</em><em> </em><em>1</em><em>3</em>
y = 3(3) - 7 <em>Substitute</em><em> </em><em>x</em>
y = 9 - 7 <em>Simply</em>
y = 2 <em>Subtract</em>
Let's check:
4(3) + 3(2) = 18
12 + 6 = 18
18 = 18
It works!
Answer: you got it right
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 35%, X is 140, so the equation is 35% * 140 = Y
Convert 35% to a decimal by removing the percent sign and dividing by 100: 35/100 = 0.35
Substitute 0.35 for 35% in the equation: 35% * 140 = Y becomes 0.35 * 140 = Y
Do the math: 0.35 * 140 = 49
Y = amount of discount= 49
So 35% of 140 is 49
140-49= sale price= 91
