Answer:
They got 12 by multiplying 3 × 4
Step-by-step explanation:
They used distributive property to multiply the 3 by each number in the parentheses
3 × x/3 = 1x = x
3 × 4 = 12
x + 12 = 6 × 3
They mutliplied 6 × 3 to get 18
x + 12 = 18
They then subtracted both sides by 12 to isolate the variable
x + 12 - 12 = 18 - 12
x = 6
Answer:
hope this helps! lmk if you still dont understand it!
:)
Step-by-step explanation:
you do 3*4 which gives you 12 and 3*x/3, but you should keep it as x
6*3 is 18
x+12=18 (solve for x)
-12=-12
x=6
check the answer:
3*(6/3+4)=6*3
3(2+4)=6*3
6+12=6*3
18=18

drops a bale of hay while the helicopter itself is rising at 32 feet per second. The height (S)
in feet of the bale as a function of time is given by:s(t) = -16t2 + vit + Si
where t is the time since the bale was dropped off the helicopters (in seconds), V is the
initial velocity, and Si is the initial height.

Find the measure of DCH.
Answers
===================================================
Work Shown:
Angles DCH and PCF are congruent because they are vertical angles.
angle DCH = angle PCF
5h+94 = 7h+80
94-80 = 7h-5h
14 = 2h
2h = 14
h = 14/2
h = 7
angle DCH = 5h+94
angle DCH = 5*7+94
angle DCH = 35+94
angle DCH = 129 degrees
angle PCF = 7h+80
angle PCF = 7*7+80
angle PCF = 49+80
angle PCF = 129
We get the same result for both angles, which confirms the correct h value.

2. 1. POINT A HAS COORDINATES (4,6) AND POINT O IS AT THE ORIGIN. FIND THE DISTANCE FROM O TO A. A 6
Answers
Answer:
√52 units
Step-by-step explanation:
Here we want to find the distance between two points;
O(0,0) and A (4,6)
We can use the distance formula to find this;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(4-0)^2 + (6-0)^2
D = √(16 + 36)
D = √52
So the distance between the two points is √52 units

Suppose you had two circular objects. Let the first circular object have a diameter of 26 cm and let second circular object have a diameter that is half as long as the diameter of the first. What would the circumference be for the second item in centimeters?
Answers
Answer:
40.82cm
Step-by-step explanation:
half of 26 is 13
the second's circle diameter is 13
the formula for circumference is C = 2πr
where r is the radius and π is 3.14
diameter =2r
13 = 2r
r = 6.5
2 x 6.5 x 3.14 = 40.82

do any of y’all know how to do number 7?
Answers
Answer:
f(-3) = 2
f(-1) = 2
f(8) = 1
Step-by-step explanation:
Yep! For any function f(x), you find the y value corresponding the x value. For example, in this question, it asks us to find f(-3). Therefore, you go to the line, x = -3, and see where it intersect the function (the y value). Your answer would be the y value.
The value corresponding to f(-3) seems to be 2.
The value corresponding to f(-1) seems to be -2.
The value corresponding to f(8) seems to be 1.
Kelly wants to decrease her daily sugar intake from 40 grams of sugar to 30 grams of sugar. By what percentage does Kelly want to decrease her daily intake of sugar? O 10% O 25% O 75% O 905
Answers
Kelly wants to reduce her sugar consumption by 25%.
Kelly wants to go from consuming 40 grams to 30 grams of sugar.
The percentage she wants to decrease by can be found by the formula:
= (Old intake - New Intake) / Old Intake
Solve the formula and the percentage is:
= (40 - 30) / 40
= 0.25
= 25%
In conclusion, Kelly wants to decrease her sugar intake by 25%.
