Answer:
1. g=0
2. t=-11
3. v=56
4. d=-27
Step-by-step explanation:
1. add 4 to both sides
2. divide both sides by -5
3. multiply both sides by -7
4. multiply both sides by -3
Answer:1) g=0
2)t=-11
3)v=56
4)d=-27
Step-by-step explanation:
1) add 4 to both sides, g=0
2)divide by -5 on both sides to isolate the variable
3) multiply by the reciprocal (opposite) of -1/7 which is -7 on both sides to get 56
4) multiply by the denominator on both sides, so -3 to get -27

What is the LCM (least common multiple) of 2 and 7
Answers
Answer:
14
Step-by-step explanation:
Answer: 14
Step-by-step explanation:
The greatest common multiple of 2 and 7 is 1, because they are both prime numbers (numbers that cannot be divided by anything other than one or themselves).
Why bother with the greatest common multiple?
There's a very sneaky formula you can do to calculate the LCM with this.
[tex]lcm(a, b) = \frac{|a * b|}{gcd(a, b)}[/tex]
where lcm(a, b) = the least common multiple of integers a and b (1)
a = integer a (2)
b = integer b (7)
gcd(a, b) = greatest common divisor of integers a and b
So let's use it, we have all the available numbers.
[tex]lcm(a, b) = \frac{|2 * 7|}{1} = 14[/tex]

Five-foot-tall Melody casts an 84-inch shadow. How tall is her friend if, at the same time of day, his shadow is 1 foot shorter than hers?
Answers
Answer:
The height of her friend is 4.826 feet.
Step-by-step explanation:
The length of the shadow ([tex]x_{S}[/tex]), measured in feet, is directly proportional to the height of the person ([tex]x_{P}[/tex]), measured in feet. That is:
[tex]x_{P} \propto x_{S}[/tex]
[tex]x_{P} = k\cdot x_{S}[/tex] (1)
Where [tex]k[/tex] is the proportionality constant, no unit.
We can eliminate this constant by constructing this relationship:
[tex]\frac{x_{P,M}}{x_{S,M}} = \frac{x_{P,F}}{x_{S,F}}[/tex] (2)
Where M and F represents Melody and Melody's friend. If we know that [tex]x_{P,M} = 5\,ft[/tex], [tex]x_{S,M} = 7\,ft[/tex] and [tex]x_{S,F} = 6\,ft[/tex], then the height of his friend is:
[tex]x_{P,F} = \left(\frac{x_{P,M}}{x_{S,M}} \right)\cdot x_{S,F}[/tex]
[tex]x_{P,F} = \left(\frac{5\,ft}{7\,ft}\right)\cdot (6\,ft)[/tex]
[tex]x_{P,F} = 4.286\,ft[/tex]
The height of her friend is 4.826 feet.

Solve 4x - 8 < 44. Enter your answer as an inequality.
Answers
Answer:
x < 13
Step-by-step explanation:
We have an inequality and are asked to solve for x.
Inequality work the same as expressions when it comes to solving for x, the only difference is that when you divide by a negative, the inequality sign changes. Which is not a problem.
4x - 8 < 44
Add 8 to both sides :
4x < 52
Divide 4 from both sides :
x < 13

Describe all numbers x that are at a distance of 4 from the number 9. Express this using absolute value notation.
Answers
Answer:
|x - 9| = 4
Step-by-step explanation:
All numbers x that are at a distance of 4 fro the number 9
Given two numbers a and B, the absolute distance between them is written as :
|a - b| = c
Hence all numbers x at distance of x from 9
|x - 9| = 4
{x : |x - 9| = 4}

Amanda and her group of friends spent a total of $35.50 on 7 hot dogs and 6 cheese burgers. Greg and his group of friends spent $30.50 at the same snack bar on 5 hot dogs
and 6 cheese burgers.
For your answer WRITE THE EQUATIONS and state how much hot dogs cost and cheese burgers cost.
Answers
5h + 6b = 30.50
The difference between the 2 totals spent is $5, and there were the same number of burgers, but 2 fewer hotdogs. So $5/2 = $2.50, the cost of a hot dog. Substitute that into the equations to solve for burgers (b)
5(2.50) + 6b = 30.50
12.50 + 6b = 30.50
6b = 18
b = 3
Check the work:
7(2.50) + 6(3) =
17.50 + 18 = 35.50

Answers
Answer:
x = 104 degrees
y = 76 degrees
z = 104 degrees
quadrilateral have to add up all of their interior angles to 360 degrees.
x and c are opposite interior angles. after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.
Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.
Answer:
m∡x = 104°
m∡y = 76°
m∡z = 104°
Step-by-step explanation:
m∡A ≅ m∡C
m∡B ≅ m∡D
to find m∡B: 2(104) + 2y = 360
208 + 2y = 360
2y = 152
y = 76
m∡z: 180° - 76° = 104°

A circular running track is
1/8
mile long. Elena runs on this track, completing each lap in
1/24
of an hour.
What is Elena's running speed, in miles per hour? Type just the number answer..
Answers
Answer:
3 miles per hour
Step-by-step explanation:
Speed is defined as the distance covered per unit time, which can be expressed mathematically as follows;
Speed = Distance/Time
The given parameters are;
The length of the circular running track = 1/8 mile
The time it takes Elena to complete a lap = 1/24 hour
Therefore, we have;
Elena's running speed = The distance Elena completes/(The time it takes Elena to complete the given distance)
∴ Elena's running speed = The 1/8 mile track/(1/24 hour)
[tex]Elena's \ running \ speed =\dfrac{\dfrac{1}{8} \ mile }{\dfrac{1}{24} \ hour } = \left (\dfrac{1 }{8} \times \dfrac{24}{1 } \right ) \ \dfrac{mile}{hour} = \dfrac{24}{8} \ \dfrac{mile}{hour} =3 \ mile/hour[/tex]
Elena's running speed = 3 mile per hour.
