Answer:
x = -2.3
Step-by-step explanation:
4x + 1.3 = -7.9
First we want to combine the like terms.
Subtract 1.3 from both sides.
4x = -9.2
Now we want to isolate x by dividing both sides by 4.
x = -2.3
Check your answer by plugging x back into the original equation.
4x + 1.3 = -7.9
4(-2.3) + 1.3 = -7.9
Multiply.
-9.2 + 1.3 = -7.9
Add.
-7.9 = -7/9
Your answer is correct.
Hope this helps!
Step-by-step explanation:
4x + 1.3 = - 7.9
4x = - 7.9 - 1.3
4x = - 9.2
x = - 9.2/4
= - 2.3

Solve for y: 3d = 7y + 5
Answer:
d = [tex]\frac{7y+5}{3}[/tex]
Step by step explanation:
3d = 7y+5
Divide both sides by 3
[tex]\frac{3d}{3}[/tex]= [tex]\frac{7y}{3}[/tex]+ [tex]\frac{5}{3}[/tex]
Simplify
[tex]\frac{7y+5}{3}[/tex]
Find the measured of the numbered angles in the rectangle. Geometry Chapter 7.4
Answer:
∠3 = 18°
∠4 = 144°
∠2 = 36°
∠1 = 72°
Step-by-step explanation:
From the concept of alternate interior angles,
∠3 = 18°
Since the diagonal divides the rectangle into 4 parts with 2 of the rectangles being similar.
Then, the triangle with ∠3 & ∠4 is an Isosceles triangle and as such;
∠4 = 180 - 2(∠3)
∠4 = 180 - 2(18)
∠4 = 180 - 36
∠4 = 144°
∠2 = 180 - ∠4 (because sum of angles on a straight line is 180°)
∠2 = 180 - 144
∠2 = 36°
Like it was done for angle ∠4 above;
∠1 = (180 - 36)/2
∠1 = 144/2
∠1 = 72°

Step-by-step explanation:
There is a 1/4 probability of getting an A out of a bag with letter MATH
For B) There are two A's our of 8 letters is ADMIRALS.
2/8 is the same as 1/4
The answer is B
A) is wrong because that 1/6
C) is wrong because that's 1/8
D) is wrong because that's 2/9
Answer:
B
Step-by-step explanation:
Probability of finding A in a word = number of A / number of letters in that word
Probability of finding A in MATH = 1/4
A. Probability of finding A in BECAME = 1/6
B. Probability of finding A in ADMIRALS = 2/8 = 1/4
C. Probability of finding A in USERNAME = 1/8
D. Probability of finding A in AFTERMATH = 2/9
So we have a match with option B
aria is saving to buy a phone.she has 85 dollars and can save an additional 10$ per week how much total money will she have after 8 weeks
Answer:
165
Step-by-step explanation:
1. you have to do 10 x 8 bc she makes 10 dollars a week, and it says how much will she make in 8 weeks so you do 10 x 8. 10 x 8 = 80 , so you take the 85 dollars she has then you take the 80 and add them together and you get 165.

Find the value of x
Answer: x is 13
Step-by-step explanation:
90 - 67 is 23. Then you figure out what times 2 minus 3 is 23. Which would be 13. 13 times 2 is 26 minus 3 is 23. 67 + 23 is 90 ( right triangle)
Answer:
x=13
Step-by-step explanation:
The two angles are complementary, meaning that they both add up to 90°.
So, since we know that one of the angles is 67°, we can find the other one by subtracting 67 from 90.
90-67=23
So the equation is equal to 23.
2x-3=23
Add 3 to both sides.
2x=26
Divide both sides by 2.
x = 13

Which of these sums is less than 1
a. 1/2 + 2/3
B. 1/3 + 1/8
C. 3/4 + 3/5
D. 4/5 + 7/10
Answer:
B will the correct answer.
Step-by-step explanation:
1/2 + 2/3 = 7/6 = 1 1/6
1/3 + 1/8 = 11/24
3/4 + 3/5 = 27/20 = 1 7/20
4/5 + 7/10 = 15/10 = 1 1/2
1 1/6 > 1
11/24 > 1
1 7/20 > 1
1 1/2 > 1

The inner diamond has congruent sides
Half of the line segment on the left is 25.
The other half of the left line segment is also 25
Together, the left line segment is 50 units
The inner diamond has both 90 degree angles and 18 unit long sides
Thus, we know that both sides are congruent
Finally, the right side is the same length as the left side
The right side is 50 units long

A certain brand of flood lamps has a lifetime that is normally distributed with a mean
of 3,750 hours and a standard deviation of 300 hours.
(a) What proportion of these lamps will last for at least 4,000 hours?
(b) What proportion of these lamps will last between 3,600 and 4,000 hours?
(c) What proportion of these lamps will last less than 3,800?
Answer:
0.83
Step-by-step explanation:
(a) z = (x - mean) / sd = (4000 - 3750) / 300 = 0.83
This corresponds to 0.7967 from the z-table, which represents how many last less than 4000 hours, so the answer is 1 - 0.7967 = 0.2033
(b) It will be P(x<4000) - P(x>3600) = 0.7967 - whatever the corresponding value is.
(c) same procedure as (b).
(d) 2% above corresponds to 0.02 which is a z-score of -2.05
-2.05 = (x - 3750) / 300
x = 3135
