3. Tim had 253 dollars to spend on 7 books. After
buying them he had 15 dollars. How much did each book cost?
Answer:
each book costs $34
Step-by-step explanation:
assuming that all the books cost the same,
253-15=238
238/7=34
Answer: Each book cost $34.
Step-by-step explanation:
First subtract 253-15.
253-15=238.
Then divide 238/7.
238/7=34

plot the flowing points on the number line without measuring.
Answer:
1/4, 3/5, 8/10
Step-by-step explanation:
3/5 is greater than 1/4
(2/4 is equal to 2.5/5---that should give you a visual picture why)
8/10 is greater than 3/5
3/5 multipled by 2 is 6/10
so, 6/10<8/10
Answer:
1/4 then 3/5 then 8/10

A transformation that maps the vertex A( 3 , 4 ) to A’ ( -4 , 3 ) is
Answer:
"A translation of 7 units to the left followed by a translation of 1 unit down".
Step-by-step explanation:
There are multiple transformations that map one point into another, here is one example that works particularly for translations, which are the simplest (and usually the most used) transformations.
Suppose that we have the point (a, b) which is transformed into (a', b')
Then we have a horizontal translation of (a' - a) units followed by a vertical translation of (b' - b) units.
(the order of the translations does not matter, is the same having first the vertical translation and then the horizontal one).
Here we have the point A (3, 4) transformed into (-4, 3)
Then we have a horizontal translation of ((-4) - 3) = -7 units followed by a vertical translation of (3 - 4) = -1 units.
Where a horizontal translation of -7 units is a translation of 7 units to the left, and a vertical translation of -1 unit is a translation of 1 unit down.
Then we can write this transformation as:
"A translation of 7 units to the left followed by a translation of 1 unit down".

Answer:
Did u ever get the answer to this?
Step-by-step explanation:
Prove that if a^x=b^y=ab^xy then x+y=1
Answer:
Below.
Step-by-step explanation:
Prove that if
a^x = b^y = (ab)^(xy) then x + y = 1.
From the second equation:
y = 1 - x
So we have:
a^x = b^y = b^(1-x)
Taking logs:
x ln a = (1-x)ln b
x ln a + x ln b = ln b
x = ln b / ( ln a + ln b)
x = ln b / ln ab.
This is true if x + y = 1.
Now consider b^y = (ab)^(xy):
b^(1 - x) = (ab)^(x(1- x)
ln b - x ln b = x(1 - x)ln ab
ln b - x ln b = x ln ab - x^2 ln ab
Now we substitute for x = ln b / ln ab in this expression.
If left side = right side then we have proved this identity and therefore the original one.
Left side = ln b - (ln b / ln ab) * ln b = ln b - (ln b)^2 / ln ab.
Right side = (ln b / ln ab) * ln ab - [(ln b)^2 / (ln ab)^2] * ln ab
= ln b - (ln b)^2 / ln ab.
Left side = right side so this identity is true, and so the original one
( x + y = 1) is true also.

-4x-16=2x+2 does anyone know what this would be
Answer:
-3
Step-by-step explanation:
-4x-16=2x+2
-4x-2x= 16+2
-6x = 18
x = 18/-6 = -3
I hope im right!!
Answer:
Step-by-step explanation:
-4x-16=2x+2
-4x-16+16=2x+2+16
-4x=2x+18

Answer: 10 feet
Step-by-step explanation:
Determine the volume and the total surface area of the square pyramid.if its perpendicular height is 12cm and square length is 5cm
Answer:
Volume = 100 cm³
Surface area of the square pyramid = 145 cm²
Step-by-step explanation:
Given:
Perpendicular height = 12cm
Square length = 5cm
Find:
Volume
Surface area of the square pyramid
Computation:
Area of base = side²
Area of base = 5²
Area of base = 25 cm²
Volume = (1/3)(A)(h)
Volume = (1/3)(25)(12)
Volume = 100 cm³
Surface area of the square pyramid = A + 1/2(P)(h)
Perimeter square pyramid = 4(s)
Perimeter square pyramid = 4(5)
Perimeter square pyramid = 20 cm
Surface area of the square pyramid = 25 + 1/2(20)(12)
Surface area of the square pyramid = 145 cm²
What is the area of the shaded region?
Answer:
12 cm^2

Directions: The points in the table lie on a line. Find the slope of the line. Then draw its graph.
Answer: Slope means the gradient. So find the equation of the line first then graph the points on the graph.
Step-by-step explanation:
y=mx+c *We want m*
m=(y2-y1)/(x2-x1)
m=(0-1)/(6-3)
m=-1/3
y=-1/3x+2 *(0,2) co-ordinate means it's the y-intercept=c*
I think the slope is -1/3 and then just plt the points on the graph manually.
please help me its hard!
Answer:
600
Step-by-step explanation:
Consider ABC and ACD as two triangles. And AC as a base to both of them
so,
AC = AO + OC
= 15 + 25
= 40
Now the area of ABC =
[tex]\frac{1}{2}\times AC\times OB\\= \frac{1}{2}\times 40 \times 10\\= 200[/tex]
In the same way, the area of ACD =
[tex]\frac{1}{2}\times AC\times OD\\= \frac{1}{2}\times 40 \times 20\\= 400[/tex]
Both added together 400 + 200 = 600

The operation * on the set Z of integers is defined by x*y = 3x + 2y - 1, x, y E Z. Find the value of x such that x*2=5
Answer:
x = 2/3
Step-by-step explanation:
Let's unpack the equation [tex]x*2=5[/tex] from our definition of [tex]*[/tex]:
[tex]x*2=3x+2(2)-1=5[/tex] (where [tex]x\in \mathbb{Z}[/tex])
Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:
[tex]3x+2(2)-1=5\\3x+4-1=5\\3x+3=5\\3x=2\\x=2/3[/tex]

1.4x + 3.5y
help! 6th grade :)
Answer:
Step-by-step explanation:
Simplifying
1.4x + 3.5y = 0
Solving
1.4x + 3.5y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3.5y' to each side of the equation.
1.4x + 3.5y + -3.5y = 0 + -3.5y
Combine like terms: 3.5y + -3.5y = 0.0
1.4x + 0.0 = 0 + -3.5y
1.4x = 0 + -3.5y
Remove the zero:
1.4x = -3.5y
Divide each side by '1.4'.
x = -2.5y
Simplifying
x = -2.5y
