Answer:
Step-by-step explanation:
Given the system of equations:
2x + 3y = 15
X + 3y = 0
What is x?
2x + 3y = 15
X + 3y = 0 subtract the bottom equation fron the top one
2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero
2x - x = 15
x = 15 Now for extra credit what is y?
X + 3y = 0
15 + 3y = 0
15 - 15 + 3y = 0 - 15
3y = -15
3y/3 = -15/3
y = -5

do 18/14 and 10/15 have the same vaule explain why
Answers
Answer:
Step-by-step explanation:
18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.
These two are not equivalent fractions
Answer:
No.
Step-by-step explanation:
Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:
18/14 > 1
10/15 < 1
18/14 > 10/15

Answers
Answer:
x ≤ 2
(when graphed, closed circle on two, shaded to the left)
Step-by-step explanation:
3/4 x - 2/3 ≤ 5/6
Add 2/3 to both sides:
3/4x ≤ 5/6 + 2/3
3/4x ≤ 3/2
Divide by 3/4 on both sides:
x ≤ 3/2 ÷ 3/4

The diagram shows the sector of a circle with the centre O and radius 6cm.
MN is a chord of the angle.
angle MON is 50 degrees
calculate the area of the shaded segment
give your answer to 3 significant figures
Answers
Answer:
Area of the shaded region = 1.92 cm²
Step-by-step explanation:
From the picture attached,
Area of the shaded region = Area of the sector OMN - Area of the triangle OMN
Area of sector OMN = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]
Here, θ = Central angle of the sector
r = radius of the sector
Area of sector OMN = [tex]\frac{50}{360}(\pi )(6)^2[/tex]
= 15.708 square cm
Area of ΔOMN = 2(ΔOPN)
Area of ΔOPN = [tex]\frac{1}{2}(OP)(PN)[/tex]
Area of ΔOMN = OP × PN
In ΔOPN,
sin(25°) = [tex]\frac{PN}{ON}[/tex]
PN = ONsin(25°)
= 6sin(25°)
= 2.536 cm²
cos(25°) = [tex]\frac{OP}{ON}[/tex]
OP = ONcos(25°)
OP = 6cos(25°)
OP = 5.438 cm
Area of ΔOMN = 2.536 × 5.438
= 13.791 cm²
Area of the shaded region = 15.708 - 13.791 = 1.917 cm²
≈ 1.92 cm²

Find the LCM
of 9 and 27.
Answers
Answer:
27
Step-by-step explanation:
The answer is 27, because 9 x 3 = 27 and the smallest number that is the same is 27.
Hope this helps!
Answer:
27
Step-by-step explanation:
LCM is the least common multiple of one or more numbers. we can find this by finding the factors of 9 and 27.
9, 18, 27, 36, 45, 54
27, 54, 81, 108
since 27 is the smallest factor of both 9 and 27, it is the least common multiple.
