Answer:
x = 25
Step-by-step explanation:
120 = 70 + 2x
120 - 70 = (70 - 70) + 2x
50 = 2x
50/2 = 2x/2
x = 25
Answer:
A=42.5
Step-by-step explanation:
First you split this shape into a square and a triangle.
The area of the square is 5✖️5=25.
Then, there is a triangle left.
We do not know about the hypotenuse, but the sides are 5 and 7.
5✖️7=35/2<-- because it is a triangle. =17.5
You add both areas, and you get the total of 42.5.
Hope this helps!
Answer:
Let's say that the whole book have 5a pages.
First day: a + 12
Second day: (4a)1/4+15= a + 15
Third day: (1/3)[ 4a - (a+15)] +18= a + 13
Forth day: 70
So we get this:
(a + 12) + (a + 15) + (a + 13) + 70 = 5a
a + 12 + a + 15 + a + 13 + 70 = 5a
3a + 110 = 5a
3a - 5a = -110
-2a = -110
a = 55
5a = 5(55) = 275
So the total pages are in the book is:
275 pages
Answer:
256m^2
Step-by-step explanation:
you can cut up the figure.
A1=bh
A1= 24x8
A1=192m^2
A2=bh
A2= bh
A2=8x8
A2=64m^2
A1+A2= Atotal
A=192+64
A=256m^2
Given the compound inequality:
Let's find the equivalent form of the inequality.
To find the equivalent form, let's simplify the inequality.
SInce it is a compund inequality, we are to seperate the inequalities.
Simplify the first two inequalities, then simplify the last two inequalities.
We have:
First two inequalities: -44 > -2x - 8
Last two inequalities: -2x - 8 ⩾ -8
Let's simplify both
Therefore, the equivalent form is:
