have a good day!!
Answer:
Step-by-step explanation:
13=3x+4
subtract 4 from both sides
9=3x
divide by 3
x=3
Step-by-step explanation:
60+55 equal 65 that my explain

Answer: MH = 7</h3>
=====================================================
Explanation:
The double tickmarks for quadrilateral MATH show that MA = TH. Since TH is 5 units long, this makes MA the same length as well.
For quadrilateral ROKS, we have RO = 15. For "MATH" and "ROKS" we have "MA" and "RO" as the first two letters of each four-letter sequence; meaning that MA and RO correspond together.
The ratio of the corresponding segments is RO/MA = 15/5 = 3.
The larger quadrilateral has each side length 3 times longer than the smaller quadrilateral's corresponding side lengths.
--------------
In short,
larger side = 3*(smaller side)
--------------
Using this scale factor of 3, we can find MH
larger side = 3*(smaller side)
RS = 3*(MH)
21 = 3*MH
3*MH = 21
MH = 21/3
MH = 7
Answer:
Choice 4 (s - 3 = 12)
Step-by-step explanation:
I think you made a reading error on this question, as it said "for which equation is s = 9 <em>not</em> the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable <em>s</em> of each equation.
1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.
2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.
3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.
4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.
Choice 4/D is the correct choice.
