The number in the blanks represents
Answers
Answer:
Blank 1 : 3
Blank 2: 3
Step-by-step explanation:
Let the unknown number for blank 1 be x.
The given problem is
Divide both sides by 4.
The answer for blank 1 is 3.
Let the unknown number for blank 2 be y.
The answer for blank 2 is 3.
The number in the blanks represents the same number.
If a number x is divided by another number m and gives the answer q without any reminder, then q is called the quotient.
Hence, the number here in blank represents the quotient.

Answers
Answer:
Step-by-step explanation:
From.the Pythagoras theorem,
DF² = DE² + EF²; therefore, DE²= DF²-EF².since each of the side of DEF is 1/3 of sides ABC , it implies that ,1/3 of 20 = 6.7 ( DF)and 1/3 of 16 = 5.3 (EF)
DE² = 6.7²-5.3²;
DE² = 44.89 - 28.09
DE² =16.8
Therefore taking the square root is both side to get the true value of DE
√DE² = √16.8; DE = 4.098.
there the value of sin of angle F
SinF°= 4.098/6.7; = 0.6116
Therefore F° = sin-¹0.6116; 37.7°.
SinF = 0.6116, while angle F = 37.7°
Note: the purpose of using the Pythagoras theorem is to help you find the third side of triangle DEF which is DE

x,y - the numbers
one positive number is 5 less than twice a second number
(1) x - 5 = 2y
their product is 117
(2) xy = 117
(1) x - 5 = 2y add 5 to both sides
x = 2y + 5 substitute it to (2)
(2y + 5)y = 117 use distributive property
(2y)(y) + (5)(y) = 117
2y² + 5y = 117 subtract 117 from both sides
2y² + 5y - 117 = 0
2y² + 18y - 13y - 117 = 0
2y(y + 9) - 13(y + 9) = 0
(y + 9)(2y - 13) = 0 ↔ y + 9 = 0 ∨ 2y - 13 = 0
y + 9 = 0 subtract 9 from both sides
y = -9
2y - 13 = 0 add 13 to both sides
2y = 13 divide both sides by 2
y = 6.5
substitute the values of y to (1)
x = 2(-9) + 5 = -18 + 5 = -13 < 0
x = 2(6.5) + 5 = 13 + 5 = 18
Answer: x = 18 and y = 6.5

If you are trying to figure out how many marbles Timmy gave away, let's see -
All you really do is divide 24 into 6 pieces, then take 1 piece and count how many is in that one piece. Let's do it -
24 ÷ 6 = 4
See? Super easy, right? 1/6 of 24 marbles is equal to four marbles.

Answer:
The product is a final result to an equation.
The sum is found by doing addition.
I need to know what the dimensions of the rectangle are, but a simplified version of it is
Algebra tiles- you ADD them up as they are to make an equation.
Generic Rectangle- You write your problems into the boxes (however many are given), then you put your answers into the boxes. You, lastly, add them up to get the SUM
