Answer:
x = 15
Step-by-step explanation:
Given
3(x - 8) + 4 - 2x = - 5 ← distribute and simplify left side
3x - 24 + 4 - 2x = - 5
x - 20 = - 5 ( add 20 to both sides )
x = 15
Answer:
x = 15
Explicación paso a paso:
Dado
3 (x - 8) + 4 - 2x = - 5 ← distribuir y simplificar el lado izquierdo
3x - 24 + 4 - 2x = - 5
x - 20 = - 5 (suma 20 a ambos lados)
x = 15

A and E, there is honestly no really steps to find this out, you just kind of think if it makes sense like you wont divide when you want to find out how many and how many is a key word to multiplication so look for multiplication like A and E.

Answer: -28 squared is the answer
red paint is 1 and blue paint is 3 how much red is there for each blue? Im low on points so u sadly only get 10
Answer:
1 quart blue + 1 1/2 quart red
Given:
Ratio of blue paint : red paint = 1/3 : 1/2
simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:
(1/3) x (3x2) : (1/2) x (3x2)
2 : 3
From this we can determine the fractions of red and blue paint used in any total purple mix
fraction of blue paint = 2/(2+3) = 2/5 of purple mix
fraction of red paint = 3/(2+3) = 3/5 of purple mix
we are given that we want to make 2 1/2 (= 5/2) quarts of purple paint
hence
amount of blue paint
= fraction of blue paint in purple mix x total amount of purple paint
= (2/5) x (5/2) = 1 quart
amount of red paint
= fraction of redpaint in purple mix x total amount of purple paint
= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart

Cy has 42 baseball cards & 70 football cards that he wants to group into packages. Each package will have the same number of cards, and each package will have the same numbers of baseball cards and football cards. How many packages will Cy make if he uses all the cards?
Answer:
The answer is 14
Step-by-step explanation:
14
Answer:
Cy has 42 baseball cards and 70 football cards
he wants to group them into packages with each package having the same number of cards of both types
so we have to find the highest common factor for 42 and 70 so they can be divided into packages equally and each package having an equal number of cards
the factors for 42 and 70 are as follows
42 - 1,2,3,6,7,14,21,42
70 - 1,2,5,7,10,14,35,70
the highest factor common for both is 14
therefore Cy can make 14 packages
each package will have
42/14 = 3 baseball cards
70/14 = 5 football cards
so each package will have 3 baseball cards and 5 football cards
Cy can make 14 packages
The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025 cm.
Part A) What is the distance from the sun to Mercury written in scientific notation?
Part B) What is the diameter of a human hair written in scientific notation?
Part C) In comparing the measurements in Parts (a) and (b), what else must be done before a comparison is made?
Answer:
Distance of Sun and Mercury = 58,000,000 km.
In Scientific notation, it would be: 5.8 × 10⁷ Km
Diameter of a human hair = 0.0025 cm
In scientific notation, it would be: 2.5 × 10⁻³ cm
Before Comparison, we need to bring to or vice-versa, so we can easily calculate then, here, we will go from cm to Km.
2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸
Now, we can compare the values,
5.8 × 10⁷ Km > 2.5 × 10⁻⁸
[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]
Answer:
58,000,000 km

While scuba diving, Rajeev dove to a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet. What expression can be used to find Rajeev’s new position?
12.6 – 8.7
–12.6 – 8.7
–12.6 – (–8.7)
12.6 – (–8.7)
The required expression is 12.6 - (-8.7) can be used to find Rajeev’s new position.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
To find Rajeev's new position, we need to add the depths of his two descents.
Since the first descent was to a depth of 12.6 feet below the surface of the water, and the second descent was to a depth of 8.7 feet below the surface of the water, Rajeev's new position is 12.6 + 8.7 = 21.3 feet below the surface of the water.
Therefore, the expression we are looking for is 12.6 + 8.7 = 21.3. This is the same as the fourth option: 12.6 - (-8.7) = 21.3.

Yannick bought a bicycle. He paid $194.25, including tax. If the sales tax rate is 5%, how much did Yannick pay for tax?
Answer:
$9.71 or $203.96
Step-by-step explanation:
5% of $194.25 is $9.71
if you wanted the overall cost that would be $203.96.
Answer:
$11.00 in sales tax
Explaination:
To find the sales tax from total bill, you would divide the total amount by "1 + the sales tax rate" (i.e., If the sales tax is 5%, divide the total amount by 1.05."
Soooo....
194.25 / 1.05 = 183.25**
** Now take that total and subtract it from the full total amount of 194.25.
194.25 - 183.25 = $11.00**
** This total is the amount of sales tax charged.**

can someone tell me how to graph [tex]y-2x=6[/tex] ?
Please help me with this problem.
Answer:
A.
Step-by-step explanation:
∠A and \angle B∠B are complementary angles. If m\angle A=(2x+30)^{\circ}∠A=(2x+30)
∘
and m\angle B=(6x-12)^{\circ}∠B=(6x−12)
∘
, then find the measure of \angle A∠A..
Answer:
∠A = 48
Step-by-step explanation:
∠A + ∠B = 90 ( Complementary angles)
2x + 30 + 6x - 12 = 90
Combine like terms
2x + 6x +30 - 12 = 90
8x + 18 = 90 {subtract 18 form both sides}
8x = 90 - 18
8x = 72 {Divide both sides by 8}
8x/8 = 72/8
x = 9
∠A = 2x + 30
= 2*9 + 30
= 18 + 30
∠A = 48
