Isolate the x in both cases. What you do to one side, you do to the other.
11x + 4 < 15
Subtract 4 from both sides
11x + 4 (-4) < 15 (-4)
11x < 11
isolate the x, divide 11 from both sides
11x/11 < 11/11
x< 1
x < 1 is your answer for the first one
-------------------------------------------------------------------------------------------------------------------
Again, isolate the x.
12x - 7 > -25
Add 7 to both sides
12x - 7 (+7) > -25 (+7)
12x > -18
Isolate the x, divide 12 from both sides
12x/12 > -18/12
x > -1.5 is your answer for the second one.

Answer:
D) division
Step-by-step explanation:
we know that a ratio is a quantitative relation between two numbers
so let's say
the ratio of boys to girls is 3:4
we know that for every 3 boys there are 4 girls
therefore it is a division operation
Answer:
w is greater than or equal to 358
The measure of ABD=180°- 54°=26°
and then the measure of ADB= x
and x + 26° + 28°= 180°, sum of anlgle in a triagle property
it means x= 180°- 26-28=126°
application of sinus law in the triangle
sin 28 / BD = sin 126/ AD = sin 26/ 25 so we can deduce that
AD= 25sin126 / sin26= 46.12
let 's consider the triangle ADC, so for finding h, we have sin 28 = h / AD
and then h = AD x sin28=21.65

I predict that the product will be less than either of the factors.
When you multiply two numbers less than ' 1 ', you are
calculating the size of a piece of a piece. It winds up being
smaller than either of the pieces.
