Answer:
(x, y) = (1, 4)
Step-by-step explanation:
Given: x+y=5 and 2x-y=-2
Solve for y and x
x+y=5; solve for y
y = 5 - x; substitute into other equation
2x-y= -2
2x - (5 - x) = -2
2x - 5 + x = -2; combine x's
3x - 5 = -2; add 5 to both sides
3x =3; divide by 3
x = 1; use this to solve for y
x+y=5
1 + y = 5; subtract 1 from both sides
y = 4
(x, y) = (1, 4)
Answer:
The smaller number is 11
Step-by-step explanation:
The question is
One number is 3 less than a second number. Twice the second number is 16 less than 4 times the first. Find the smaller of two numbers
Let
x and y the numbers
x=y-3 ----> equation A
2y=4x-16 ----> equation B
Substitute equation A in equation B and solve for y
2y=4(y-3)-16
2y=4y-12-16
4y-2y=12+16
2y=28
y=14
x=14-3=11
<span>(1 + 5 ) x 2 = 12 1
+ [(5 x 2) – 2] = 10 </span>
<span>1 + [5 x (2 – 2)] = 1 [1
+ (5 x 2)] – 2 = 9</span>
<span>8 = 12 – [8 / (4 / 2)] 11 = 12 – [(8 / 4) / 2]</span>
<span>½ = [(12 – 8 ) / 4] / 2 20
= 6 x 4 – 4 x 5 </span>ß----can’t figure it out …sorry
<span>0 = 6 x
(4 – 4) x 5 100
= [(6 x 4) – 4] x 5</span>
<span>24 = [14 –(8 -2)] x 3 0=
(14 –8) – (2 x 3)</span>
<span>12 = [{14 – 8)
- 2] x 3 12
= 14 – [8 - (2 x 3)]</span>
Answer:
B
Step-by-step explanation:
11q + 5 ≤ 49
Subtract 5 from each side
11q + 5-5 ≤ 49-5
11q ≤44
Divide each side by 11
q ≤44/11
q≤4
There is a close circle at 4 because of the equals sign and the lines goes to the left
Answer:
P(B|A) means "Event B given Event A" In other words, event A has already happened, now what is the chance of event B? P(B|A) is also called the "Conditional Probability" of B given A.
