-9 + 5y - 7y + 3y = ?
Answer:
-9 + y
Step-by-step explanation:
For this problem, you have to combine like terms.
-9 is the only number that doesn't have a variable.
5y, -7y, 3y have all the the same variables, so we'll combine those.
5y - 7y = -2y
-2y + 3y = 1y
Solution: -9 + y

What is 12/15 = ab/20
(geometry converse of pythagorean theorem)
Answer:
31
Step-by-step explanation:
In circle S: XB and XD are tangents at B and D
then SB perpendicular to AX and SD perpendicular to XC
In triangle SDX: SD = 12 and SX =20 by using Pythagoras Theorem
XD = XB tangents to circle S from point X
XA = XC tangents to circle R from point X
then BA = DC = 15
then XC = XD + DC = 16 + 15 = 31
(3z+1)+5+7z) Step by step explanation needed
Answer: 10z + 6
Step-by-step explanation:
this is a short problem.. sometimes you would need to distribute, but since there is no number in front of parenthesis you can just get rid of them
that gives you: 3z + 1 +5 + 7z
now from here we combined liked terms
7z + 3z = 10z
1 + 5 = 6
so that gives you: 10z + 6

Quadrilateral IJKL is similar to quadrilateral MNOP. Find the measure of side NO. Round your answer to the nearest tenth.
Answer:
[tex]NO = 66.9[/tex]
Step-by-step explanation:
Given
See attachment for quadrilaterals IJKL and MNOP
Required
Determine the length of NO
From the attachment, we have:
[tex]KL = 9[/tex]
[tex]JK = 14[/tex]
[tex]OP = 43[/tex]
To do this, we make use of the following equivalent ratios:
[tex]JK : KL = NO : OP[/tex]
Substitute values for JK, KL and OP
[tex]14 : 9 = NO : 43[/tex]
Express as fractions
[tex]\frac{14}{9} = \frac{NO}{43}[/tex]
Multiply both sides by 43
[tex]43 * \frac{14}{9} = \frac{NO}{43}*43[/tex]
[tex]43 * \frac{14}{9} = NO[/tex]
[tex]\frac{43 * 14}{9} = NO[/tex]
[tex]\frac{602}{9} = NO[/tex]
[tex]66.8889 = NO[/tex]
[tex]66.9 = NO[/tex] --- approximated
[tex]NO = 66.9[/tex]

A full glass of water can hold 1/8 of a bottle.
How many glasses of water can be filled with 5 1/2 bottles of water?
5 1/2 bottles of water can fill 44 cups.
Step by Step Explanation:
First, lets start by making 5 1/2 an improper fraction. It would look something like this [tex]\frac{11}{2}[/tex]
From here, lets multiply it by [tex]\frac{4}{4}[/tex] so it's a number over an eighth so it's easier to understand. From this, we get: [tex]\frac {44}{8}[/tex]
Since we know that 1/8 of a bottle fills a cup, we can divide 44/8 by 1/8 to get us 44 full cups.

Step-by-step explanation:
Chelsea is 55 3/ 4 inches tall. Carl is 1 3 /8 inches taller than Chelsea and Jane is 1 1 5 inches taller than Carl. How tall is Jane?
Answer:
Height of Jane = [tex]58\frac{13}{40} inches[/tex]
Step-by-step explanation:
Given:
Height of Chelsea = [tex]55\frac{3}{4} inches[/tex]
Height of Carl = Height of Chelsea + [tex]1\frac{3}{8} inches[/tex]
Height of Jane = Height of Carl + [tex]1\frac{1}{5}inches[/tex]
Find:
Height of Jane
Computation:
Height of Carl = Height of Chelsea + [tex]1\frac{3}{8} inches[/tex]
Height of Carl = [tex]55\frac{3}{4} inches[/tex] + [tex]1\frac{3}{8} inches[/tex]
Height of Carl = [tex]57\frac{1}{8} inches[/tex]
Height of Jane = [tex]57\frac{1}{8} inches[/tex] + [tex]1\frac{1}{5}inches[/tex]
Height of Jane = [tex]58\frac{13}{40} inches[/tex]
