To solve y, we need to make y the only value on the left hand side of the equation:
Therefore the value of y = -14+3x.
Hope it helps!
Answer:
0.4545 kgs.
Step-by-step explanation:
Given that 1 kg weighs approximately 22 pounds.
i.e. 1kg= 22 lbs.
We can use this to convert lbs into kg.
22 lbs = 1 kg
Hence 1 lb = 1/22 = 0.04545 kg
Now to find out the equivalent weight for 10lbs,
we have conversion factor as 1 lb= 0.04545 kg
Hence 10 lbs = 10(0.04545) = 0.4545 kgs
Hence 10 pounds written in equivalent kgs would be0.4545 kgs.
Answer:
7/24
Step-by-step explanation:
2/3 - 3/8
2/3 + -3 / 8
16 / 24 + -9 / 24
16 + -9 / 24 = 7/24 (already simplest form, decimal form is 0.291667)
Answer:
m∠SWX=39°, and m∠VWY=51°
Step-by-step explanation:
∠XWU and ∠VWY are vertical angles. Vertical angles are congruent.
∠XWU=∠VWY
we are given ∠XWU=(7x+2)° and ∠VWY=(4x+23)°, so:
7x+2=4x+23
3x+2=23
3x=21
x=7
Now substitute x for 7 in both expressions to get the measures of the angles.
∠XWU=(7(7)+2)°=(49+2)°=51°
∠VWY is also 51° because it is congruent to ∠XWU, but just to make sure:
∠VWY=(4(7)+23)°=(28+23)°=51°
we also need ∠SWX. We can see it makes a right angle with ∠XWU, so their sum is 90°.
∠SWX+51=90
∠SWX=39°
Answer:
9 cm, 7 cm, 6 cm and 8 cm
Step-by-step explanation:
The perimeter is the sum of all the sides.
4 sides' expressions are given, so we add them and equate to 30.
Note: we disregard the value of x = -6, because it is going to give us side with negative length, that can't happen!
So, we take x = 4
Hence, length of each side is:
x + 5 = 4 + 5 = 9 cm
x + 3 = 4 + 3 = 7 cm
2x -2 = 2(4) - 2 = 8 - 2 = 6 cm
x^2 - 2x = (4)^2 - 2(4) = 16 - 8 = 8 cm
These are the lengths of 4 sides: 9 cm, 7 cm, 6 cm and 8 cm.
