Answer:
Molly would be 1 years old.
Step-by-step explanation:
"In three years..."
(m+3) will be Molly's age then.
(h+3) will be Heidi's age then.
(h+3) = 2(m+3) :: given.
.
Subsitute what we know about m, which is it equal h-4.
.
(h+3) = 2(m+3)
(h+3) = 2m + 6
substitute m=h-4
(h+3) = 2(h-4) +6
h +3 = 2(h -4) +6
h +3 = 2h -8 +6
h +3 = 2h -2
h = 2h -8 +3
-h = -5
h = 5
Heidi is 5 years old now.
.
m = h-4
m = 5-4
m = 1
Molly is 1 years old now.

Are my answers correct, if not can you explain why?
Answer:
the first one would actually negative because to the left is negative and to the right is positive. and you got the y wrong, that is actually a 2 because you dont include the line you count from, making it (-3,2).
the second one would be perfectly correct.
the third one is actually (-2,-2) and i have no idea how you got that answer, how you would count it 0, its to the left -2 and down -2.
the fourth one, would be actually (-6,-1), remember, a point goes (x,y)
What is the equation of the line that passes through the point (-2, -2) and is perpendicular to the line y = 2x+5
product of two perpendicular line slopes must equals - 1 ;
As you know the coefficient of x is the slope of the line
Thus if we suppose that line has a slope of m , we have :
m × 2 = - 1
m = - 1 / 2
__________________________________
y = ax + b
y = - 1 / 2 x + b
The line passes through the point ( - 2 , - 2 ) thus :
- 2 = - 1 /2 × ( - 2 ) + b
- 2 = 1 + b
b = - 3

y = - 1/2 x - 3

How do I do GCF (greatest common factor on -5y - 35? I need help because I am not good at it.
Answer:
-5(y+7)
Step-by-step explanation:
Well, the numbers you can divide 5 with are 1 and 5.
35 divides both with 1 and 5 too, but since 5 is the greatest, you choose 5.
so,
you divide both with -5, since both are negative.
-5y/-5 = y
-35/-5 = 7
so,
-5(y+7)
check:
-5*y = -5y
-5*7 = -35
so,
-5y-35, that's true.
Answer:
GCF = 5
Step-by-step explanation:
for the values 5, 35
Solution by Factorization:
The factors of 5 are: 1, 5
The factors of 35 are: 1, 5, 7, 35
Then the greatest common factor is 5.

4 less than four times a number is equal to three times the same number plus 1
Answer:
5Step-by-step explanation:
let x be the number we are looking for
Mathematically the statement “4 less than four times a number”
means 4x - 4
Mathematically the statement “three times the same number plus 1”
means 3x + 1
Statement 1 is equal to statement 2
means 4x - 4 = 3x + 1
We got an equation and we need to solve it :
4x - 4 = 3x + 1
⇔ 4x - 3x = 1 + 4
⇔ x = 5
In 2018 there were 238 Republicans and 201 Democrats in the House of Representatives. Find the percentage of Democrats in the House of Representatives in 2018
Answer:
45.7% or if rounded, 46%
Step-by-step explanation:
1st, you add up the total of people in the House of Representatives.
238+201=439
Then divide the number of Democrats 201 by the total number 439 to get .457 which is 45.7% or if you need to round 46%
To double check, multiply the total number 439 X 45.7% to get 200.6

Subtraction is a mathematical operation. The best policy to buy is a 20-year term policy.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Since we want the policy to last till the younger child is 22 years. And the present age of the younger child is 3 years. Therefore, the period for which the policy must work is 19 years (22-3).
Therefore, the best policy to buy is a 20-year term policy.

a. How can Kiran know for sure that Andre's
solution is incorrect?
b. Describe Andre's error and explain how to
correct his work.
Answer:
Step-by-step explanation:
Kiran can know for sure that it is incorrect by substituting x with 1/4
Solving for the equation gives 4(1/4 + 3) = 7
distributing gives 1 + 3 = 7
obviously this is incorrect
b)
Andre's error is that he didnt distribute 7
Distributing 7 results in
4x + 12 = 7
then subtracting 12 from both sides
4x = -5
x = -5/4
Answer:
x=-1.25
Step-by-step explanation:
well he was wrong about the 4x = 1.
4(x+3)=7
4x+12=7 1. - 12 on both sides
4x=-5 2. 4 on both sides
x=-1.25
Finding Angles (Level 1)
Delta Math
#highschool
Answer:
∠ E = 43°
Step-by-step explanation:
∠ BGE and ∠ FHC are alternate exterior angles and are congruent , then
∠ BGE = 119°
the sum of the 3 angles in Δ BGE = 180°, that is
∠ E + 18° + 119° = 180°
∠ E + 137° = 180° ( subtract 137° from both sides )
∠ E = 43°
Answer:
43
Step-by-step explanation:
so, it gives your angle FHC and angle B. remember B because it is important a little later, so you know that angle FHC=119. and if you remember learning congruent angles, you would know that angle HGA also equals 119 because they are corrisponding angles. so, you know they are corrisponding, how does that help you? well, if you remember learning that vertical angles are congruent, then it tells you that FHC=HGA, also meaning that HGA=119. and remember how you know that angle B=18? this also helps because you know that a triangles angles always equal 180, so you simply add 119+18=137 degrees, and you want the unknown angle being m<E and which to find you simply subtract 180-137=43 so, M<E=43 because subtracting 180-137 gives you the unknown.
