Answer:
X=12
Step-by-step explanation:
Isolate the variable:
4x/4 = 48/4
Simplify:
X=12
Hope this helps!
Answer:
x = 12
Step-by-step explanation:
Step one: Inverse the equation to eliminate the coefficient*.
*The coefficient is the number or variable that multiplies another variable (associated with it). In this case, it is four that is the coefficient.
48/4 = 12
x = 12
Check for answer:
4*12 = 48
The answer is x = 12.
Hope this helped. Have a great day.

A tower 15m high casts a shadow 30m long. A nearby telephone pole casts a shadow 16m long. Find the height of the telephone pole. Plz show ur work, thx slatttttt
Answer:
8 feet.
Step-by-step explanation:
If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio
[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.
Hope this helped!

pick a number between 30 and 100
1. −2x + 6 = -16
2. -10 + 5x = -45
Can you help me?
Answer:
for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2
getting -2x/-2=-22/-2 then you simplify that and get x=11
and for the second one x=-7. first, you have to add 10 to both sides
(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

Answer:
Point Form:
(-1/4, -7/8)
Equation Form:
x= -1/4, y= -7/8
Step-by-step explanation:
Answer:
x=-4, y=-6.5
Step-by-step explanation:
First, we need to find the value of x so
x+2=-2
-2 -2
x=-4
now plug the value of x, in the second equation
-3(-4)+2y=-1
12+2y=-1
minus 12 from both sides
12+2y=-1
-12 -12
2y=-13
divide by 2 to get the value of y
y=-6.5

whats the measure of the angles (SHOW YOUR WORK so I can understand)
Answer:
Angle DEB: 52
Angle ADB: 30
Angle CBE: 52
Angle BEC: 38
Step-by-step explanation:
Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.
