Answer:
3 x + 24
Step-by-step explanation:
(7x)-6=-12 7 times a number is 7x or 7 times any variable. Six less than that is subtracting by 6 then it all equals -12
X+2y=4
3x-2y=4
4x=8
x=2
2+2y=4
2y=2
y=1
y=1
x=2
Hope this helps :)
Answer:
7/11 (Simplified Already)
Step-by-step explanation: 25÷2235=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
25×3522=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
2×355×22=70110
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 70 and 110 using
GCF(70,110) = 10
70÷10110÷10=711
Therefore:
25÷2235=711
Solution by Formulas
Apply the fractions formula for division, to
25÷2235
and solve
2×355×22
=70110
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(70,110) = 10
70÷10110÷10=711
Therefore:
2/5÷22/35=7/11
Answer:
(0, 33) : Yes
(4.8, 30.5) : Yes
Step-by-step explanation:
height of at least 24 ft : y >= 24
horizontal distance of no more than 10 ft. : 0 <= x <= 10
The vertical height must be at least three times as high as the horizontal distance. No rocket should go higher than 33 ft.:
y >= 3x and y <= 33
So Constraints:
24 <= y <= 33
y >= 3x
0 <= x <= 10
Now check to see if those coordinate points meet all the constraints
(0, 33) : Yes
(4.8, 30.5) : Yes
(9, 26) : No (because 26 is less than (3 * 9) = 27)
(4, 36)
: No (because 36 > 33, must be 24 <= y <= 33)
(2, 22): No (because 22 <24, must be 24 <= y <= 33)
