Answer:
no solution
Step-by-step explanation:
4(9x + 4) = 36x - 7 ← distribute parenthesis on left by 4
36x + 16 = 36x - 7 ( subtract 16 from both sides )
36x = 36x - 23 ( subtract 36x from both sides )
0 = - 23 ← False statement
This indicates the equation has no solution
A drill press operator requires 1 2/3 minutes to drill through 1 inch of steel. How long will it take him to drill through four-fifths inch of the same steel?
Answer: It will take him 1.3
Step-by-step explanation:
1 2/3 divided by 5 is 0.333
0.333 times 4 is 1.3
Find the unknown sizes of angles in the following figure (I need step by step explanation and i might give brainliest):
Answer:
x = 54° , y = 29°
Step-by-step explanation:
The sum of the 3 angles in Δ ABC = 180° then
x = 180° - (72 + 54)° = 180° - 126° = 54°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of Δ CQR , then
y + 25° = x
y + 25° = 54° ( subtract 25° from both sides )
y = 29°
Answer:
x = 54
y = 29
Step-by-step explanation:
First, find the magnitude of x. To do this, add the angles inside triangle ABC, which means to add 72 + 54 + x which is equal to 180 because of the rule, the sum of the interior angles of a triangle is 180. So, when the equation is simplified, you get the answer as x = 54. Then, find the magnitude of y. The magnitude of an angle drawn around a point on a straight line is always 360, and the magnitude of the same point, but only on one side of the straight line is always 180. So, we can say that the unnamed angle in the triangle CQR is 180-x, which means 180-54 because we got x as 54 earlier. Therefore, the magnitude of the unnamed angle is 126. Now, apply the same rule we used before, the sum of the interior angles of a triangle is 180, to the triangle QCR. 25 + 126 + y = 180. When this is simplified, 29 is obtained.
To find x,
72 + 54 + x = 180 (the sum of the interior angles of a triangle is 180)
126 + x = 180
126 + x - 126 = 180 - 126
x = 54
To find y,
25 + 126 + y = 180
151 + y = 180
151 + y - 151 = 180 - 151
y = 29
The ratio of boys to girls in Mrs Ronaldo's math class 3 to 1. What percent of the class is girls?
Explanation:
Let's say this class has 3 boys and 1 girl. That means we have 3+1 = 4 students total. The percentage of girls is 1/4 = 0.25 = 25%
Find the equation of the line that passes through (1,4) and is parallel to3x+y+2=0
Answer:
y=-3x+7
Step-by-step explanation:
Step 1:
Make your thing into y=mx+b
3x+y+2=0 is the same as y=-3x-2
Step 2:
Plot your point at (1, 4)
Step 3:
Plot different points using your slope of rise 3 move 1 (remember you have a neg slope so keep that in mind)
Step 4:
Draw your line thru the points.

(a) What additional information is needed to prove the triangles are congruent by ASA Postulate? Explain.
(b) What additional information is needed to prove the triangles are congruent by the HL Theorem? Explain.
Answer:
A)
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
B)
H-L (Hypotenuse-Leg) Congruence Theorem. If the hypotenuse and leg in one right triangle are congruent to the hypotenuse and leg in another right triangle, then the two triangles are congruent.

Solve k - 120= 768 Find the value of k
Answer:
[tex]k - 120 = 768[/tex]
add 120 to both sides of the equation
[tex]k - 120 + 120 = 768 + 120[/tex]
120 on the left hand side of the equation cancels therefore isolating the variable, k
[tex]k = 888[/tex]

Answer:
52.5
Step-by-step explanation:
Just subtract 65-12 which is 53. Take away 0.5 to get 53.5
Answer:
The sunflower was 52.9 inches when the gardner last measured.
Step-by-step explanation:
a) x + 12.1 = 65 in.
b) To solve this problem, use inverse operations to find x variable. Since this problem has addition, we will have to use subtraction. 65 - 12.1 = 52.9. So, 52.9 would be your answer.

Help please!! Geometry
Applying angle pair relationships
Answer:
m∠2 = 75°
m∠1 = 105°
Step-by-step explanation:
1. First, we should recognize that the angle that's 75° and ∠2 are alternate interior angles, formed on the interior of the opposite sides of the transversal. Alternate interior angles are congruent, so m∠2 = 75°.
2. Next, ∠2 and ∠1 are a linear pair, meaning their angle measures add up to 180°. Considering that m∠2 is 75 degrees, we just have to subtract 75 from 180, and we get the measure of ∠1.
[tex]180-75[/tex] [tex]105[/tex]Therefore, m∠1 = 105°.

pls help me i don’t get this at all
Step-by-step explanation:
oh, come on ! you don't understand what ordered pairs or point coordinates stands for ?
it is simple, the first number is the x value, and the second number is the y value.
so, all we need to do here is to take every pair, put their values in the places of x and y in the inequality, and see if it is true with these specific values or not.
if yes, then that pair is a solution.

find the decimal equivalent of ¾ ounce to the thousandths place
0.75
Explanation:
Every 1/4 is 25. If you want to calculate them, then you're going to need 1/4 to find 25. In some other cases, 25, can also be written as another decimal. Such as, 4/100.
100/4 is 25. For example:
Woah! You have 3/4 of a dollar. You're really saving up money fast!
This example means that the person has 75 cents.
For an ounce, that would mean 0.04 pounds.

Solve the equation.
b^2 = 48
Answer:
b=6.92820323
Step-by-step explanation:
To find b, you would do the opposite from ^2 which is the square root. So the square root of 48. That is 6.92820323
Answer:
b ≈ 6.928 or 4√3
Step-by-step explanation:
b² = 48. To find b, we need to square root both sides (we are doing the opposite of squaring):
b = √48 = 4√3 or ≈ 6.928
