Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.
Answer:
So, the first solution is a calculator but sometime we don't have a calculator so, do
200 X 300 = A
40 X 90 = B
9 X 8 = C
then add just do multiplication from there like
A + B = D
D + C = E
Then your finally answer would be E
Hope that helps that's the way I do math quick in my head
(Btw the answer to 249 X 398 = 63,672 )

Which of the following is equivalent to the expression 2 ( 8y + 1/2 ) Select all that apply.
Answer:
B and C both are equivalent to the expression
Answer:
B, C
Step-by-step explanation:
2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.
2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.

Answer: y = 4 and x = 1
Step-by-step explanation:
when y is 2, x is 0.5
when y is 4, x is 1
.(+ 2) .(+ 0.5)
.(+ 2) .(+ 0.5)
.(+ 2) .(+ 0.5)
.(+ 2) .(+ 0.5)
the rule is that y is 4 times larger than x

Ravi had 124 dollars to begin with. He just spent b dollars. Using b , write an expression for the number of dollars he has left.
An expression for the number of dollars he has left is: 124 - B = T
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
We know that Ravi has 124$, we don’t need how much he spent So, for the money he’s spent we are using B to represent it.
The expression is:
124 - B = T
Consider that B is how much money he spent.
T is his total after.

The design plans for a new concert hall show elevations relative to ground level at 0 feet. The elevation of the balcony floor is 37 feet, and the elevation of the basement floor is –17 feet.
Which TWO statements about the distances of the balcony and basement from ground level are true?
Select TWO that apply.
A
The basement floor is 17 feet above ground level.
B
The balcony floor is 37 feet above ground level.
C
The balcony floor is 37 feet below ground level.
D
The basement floor is 17 feet below ground level.
Answer: B and D
Step-by-step explanation:
-17 means below, so the basement floor is 17 below ground level, and no symbol means positive, meaning above, so the balcony is 37 feet above ground level.
Jake is wrapping a gift that is in a box with the following dimensions.
Length: 12 inches
Width: 4 inches
Height: 8 inches
Havana is wrapping a gift whose box's dimensions are all twice the length of the lengths in Jake's box.
How many times larger is the surface area of Havana's box than Jake's box?
Enter your answer as a number, like this: 42
HELP PLEASEEEEEEEE
Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.

9. Andrew was measuring the height of the tree in his yard. Four years after it was planted, the tree was 11 feet tall. Twelve years after the tree was planted, it was 21 feet tall. Assuming the tree was growing at a constant rate, create the equation that models that growth of the tree over time. Show or explain your reasoning. (HINT: Use the two points to find the slope and use point-slope form to create an equation.)
Answer:
y=10/8x+6
Step-by-step explanation:
This is because when you plot the points you can find the slope by using rise over run and by finding the slope you can find the y intercept and that is all you need for the equation.
Answer:
first it show 11ft over 4 years so do 11/4 the answer would be 2.75 ft every year and to try doing it with the tree in 12 years

Answer:
-2
Step-by-step explanation:
i just took the test
The value of the x is -2 after solving the linear equation by using the elimination method.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear equations are:
2x+3y=8
6x−5y=−32
3X(2x+3y=8)
6x + 9y = 24
6x−5y=−32
14y = 56
y = 4
x = -2
Thus, the value of the x is -2 after solving the linear equation by using the elimination method.
