Answer:
4.66
Step-by-step explanation:
Cause 4 would be 4.0 and then you take 100 and divide by the denominator and you get .33 for every 1/3. Since you have 2/3 it would be .66, then your answer would be 4.66
Substitution Method
2x+5y=-1
y=3x+10

Answer:
C. x > -7 and x <= 3
Step-by-step explanation:
-3 < x + 4 <= 7
Subtract 4 from the three expressions.
-7 < x <= 3
-7 < x means x > -7.
Then you have x <= 3.
Answer: C. x > -7 and x <= 3
1. What is the area of a circle with a a diameter of 20 cm in terms of pi?
2. What is the area of a circle with a radius of a 8 yd using 3.14 as pi?
3. The area of a circle in terms of pi is 49pi. What is the radius of the circle?
Help needed and it would be appreciated
Answer:
1. 100pi cm
2. 200.96 yd
3. 7
Step-by-step explanation:
1.) diameter = radius multiple by two (D = r × 2)
&
radius = diameter divided by two (r = D ÷ 2)
So
20 ÷ 2 = 10 => A = pi (10)power 2 => A = 100pi
---------------------------------------------------------------------------------------------
2.) 3.14 × (8)power2 =200.96
---------------------------------------------------------------------------------------------
3.) A = 49pi => 49pi = pi(r)power2
[ cross out the pi from both sides]
And your left with
49 = (r)power2
[square root both sides to get rid of the power]
And your left with
7 = r

please answer quickly
Step-by-step explanation:
Supplementary angles add up to 180°. so,
2x+15 + 3x+5 = 180
5x+20=180
Subtract 20 from both sides
5x=160
Divide both sides by 5
x=32
Plug that into 2x+15, F = 64+15 = 79
for 3x+5, G = 96 +5 = 101

Answer:
[tex](y - 1)(x + y + 1)[/tex]
Step-by-step explanation:
[tex]y(x + y) - 1(1 + x)[/tex]
Lets expand it.
[tex] = > xy + {y}^{2} - x - 1[/tex]
Lets re-arrange it.
[tex] = > xy - x + {y}^{2} - 1[/tex]
Lets split [tex] {y}^{2} - 1[/tex]
So,
[tex] = > x(y - 1) + (y + 1)(y - 1)[/tex]
[tex] = > (y - 1)(x + y + 1)[/tex]

What single decimal multiplier would you use to decrease by 6% followed by a 7% increase?
Answer:
the single decimal multiplier is 1.0058
Step-by-step explanation:
Let us have 100
Decreasing by 6% will be
100 - 0.06(100)
= 94
Increasing by 7%
= 94 + 0.07(94)
= 100.58
So
to get the single decimal multiplier,
we have 100.58/100 = 1.0058

Answer:
Step 1, all the exponents are increased by 4
Step-by-step explanation:
The first incorrect step occurred in Step 1, where all the exponents were increased by 4.
This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.
For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.
We multiply the exponents instead of adding them together.
Therefore, the correct Step 1 should multiply all the variables' exponents by 4.
Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.
