Answer:
6 7/8 inches
Step-by-step explanation:
The first thing to do is to get the measurements in either inches or feet. You can't have both. Let's go from feet to inches.
3 feet = 36 inches
13.75 feet = 165 inches
Now we can set up a proportion to solve for the number of inches the model is:
Now we can cross multiply:
36x = 247.5 so
x = 6.875 or 6 7/8 inches
Answer:
2<em>x </em>+ 7 = 25
<em>x </em>= 7
Step-by-step explanation:
Gary: 25
Sean: <em>x</em>
----------------------------
Let's break down the sentence into mathematical terms
Gary <u>is</u> 25 years old. That <u>is</u> 7 more than twice <u>Sean's age.</u>
In math, is means equal to. It is represented with an equal sign (=)
Gary = 25. 25 = 7 more than twice <u>Sean's age.</u>
7 more is represented by 7 +
Gary = 25. 25 = 7 + than twice <u>Sean's age.</u>
Twice means double which is 2 ·
Gary = 25. 25 = 7 + 2 · <u>Sean's Age</u>
<u>Sean's Age</u> will be represented by <em>x</em>
Gary = 25. 25 = 7 + 2<em>x</em>
We don't need it to say<em> "Gary = 25" </em>in our equation.
25 = 7 + 2<em>x</em>
Let's rewrite it with the associative property.
2<em>x </em>+ 7 = 25
---------------------
Now, solve
2<em>x </em>+ 7 = 25
<em>-7 -7</em>
2<em>x</em> = 18
<em>÷</em><em>2 </em><em>÷</em><em>2</em>
<em>x </em>= 7
----------------------
Sean is 7 years old.
Answer:
4/3c^4 -it wont let me put it as it shows on your screen but the 4 is on top and under the line is 3c^4,
Step-by-step explanation:
Cancel the common factor of c^3 and z^7 -im not sure if this is what you were trying to get but its a answer-
Ok so remember that a circle is 360 degrees and a line is 180 degrees
so
IKJ
ok so we see that we have a triangle
to find the internal angles (which add to 180)
we do, opposite angles are equal
JIK=59
also CJI+KJI=180 so 132+KJI=180, KJI=48
so
59+48+IKJ=180
73=IKJ
HIB
we can assume that AB is paralell to CD
so therefor IJK=HIB=48 (from previous question)
EIJ is adding to EIH to get 180
EIJ+59=180
EIJ=121
AIK=AIJ+JIK
JIK=59
AIJ=HIB=48
AIK=59+48=107
IKJ=73
HIB=48
EIJ=121
AIK=107
