Answer:
x=-2/3
Step-by-step explanation:
[tex]7x+5=4x+3\\3x+5=3\\3x=-2\\x=\frac{-2}{3}[/tex]
Answer:
Step-by-step explanation:
7x + 5 = (4x + 3)
remove parentheses, they aren't needed here:
7x + 5 = 4x + 3
group them (subtract 5 and 4x from each side):
7x - 4x = 3 - 5
simplify:
3x = -2
divide both sides by 3:
x = -2/3

Answer:
CBA = 53°
DBC = 39°
Step-by-step explanation:
You have 2 angles, CBA and DBC.
Together, these form the angle DBA. (See attached image)
We know the following about the 2 angles:
CBA = 8x - 3
DBC = 5x + 4
Like we said, both of these together form the angle DBA. Thus:
DBA = CBA + DBC
Let's put in the values we know, 8x-3, 5x+4, instead of CBA and DBC:
DBA = 8x - 3 + 5x + 4
DBA = 13x - 3 + 4
DBA = 13x + 1
We also know that:
DBA = 92 (from the question)
Let's set our expression 13x + 1 equal to 92.
DBA = 13x + 1
DBA = 92
13x + 1 = 92
Subtract 1 from both sides:
13x = 91
Divide both sides by 13:
x = 91 / 13
x = 7
Now that we know x, we can find what CBA and DBC are.
CBA = 8x - 3
Replace x with 7:
CBA = 8*7 - 3
CBA = 56 - 3
CBA = 53
DBC = 5x + 4
Replace x with 7:
DBC = 5*7 + 4
DBC = 35 + 4
DBC = 39
Answer:
CBA = 53°
DBC = 39°

What is 18 – 0.5p = –13.5???
Answer:
p = 63
Step-by-step explanation:
Stage 1: Simplify the two sides of the condition.
18−0.5p=−13.5
18+−0.5p=−13.5
−0.5p+18=−13.5
Stage 2: Subtract 18 from the two sides.
−0.5p+18−18=−13.5−18
−0.5p=−31.5
Stage 3: Divide the two sides by - 0.5.
−0.5p
−0.5 = −31.5 , −0.5
p=63

On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a bank are located at A(−3, 1), B(1, 4), and C(5, −2). A bank employee drives from Branch A to Branch B and then drives halfway to Branch C before getting stuck in traffic. What is the minimum total distance the employee may have driven before getting stuck in traffic? Round to the nearest tenth of a mile if necessary. The minimum total distance the employee may have driven before getting stuck in traffic is?
Answer: 8.6 miles
Step-by-step explanation:
The distance between Branch A and Branch B is given by the Pythagoras theorem
AB² = (Vertical Distance)² + (Horizontal Distance)²
AB² = (4-1)² + (1 - -3)²
AB² = 3² + 4²
AB² = 9 + 16
AB² = 25
AB = 5
BC² = (Vertical distance)² + (Horizontal distance)²
BC² = (-2 - 4)² + (5-1)²
BC² = (-6)² + (4)²
BC² = 36 + 16
BC² = 52
BC = 7.21
Half way of BC = 7.21 ÷ 2 = 3.6 miles
Total distance travelled from A to B and then halfway from B to C is 3.6+5 = 8.6 miles

Solve 2(x + 1) = 2x + 5. All real numbers No solution 0 3
Answer: No solution 0=3
Step-by-step explanation:
2(x+1)=2x+5
Step 1: Simplify both sides of the equation.
2(x+1)=2x+5
(2)(x)+(2)(1)=2x+5(Distribute)
2x+2=2x+5
Step 2: Subtract 2x from both sides.
2x+2−2x=2x+5−2x
2=5
Step 3: Subtract 2 from both sides.
2−2=5−2
0=3

Due to delays, a company had to extend a project from 64 days to 123 days. What was the percentage increase in time to complete the project? Round your answer to the nearest tenth.
Answer:
40%
Step-by-step explanation:
48% is the increase in time to complete the project
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Due to delays, a company had to extend a project from 64 days to 123 days
We need to find the percentage of increase in time to complete the project.
To find this we have to find the difference and divide with actual time
123-64/123
59/123=0.479
Now we have to multiply with 100 as it is a hundredth part
0.479×100
47.9=48
Hence, 48% is the increase in time to complete the project

in order to make some extra money in the summer you water your neighbors lawn and walk their dog.your neighbor pays you $5 each time you walk the dog and $6 each time you water the lawn . when you do both jobs on the same day she gives you an extra $3 , on june 1, you dont have to complete either job, because your neighbor did them bith the day before . if you worked for your neighbor from june 1 to july 20 (thre are 30 days in june and 31 days in july), how many times would you do both jobs on the same day? How much in total would you earn from your neighbor from june 1 to July 20th?
Complete question :
In order to make some extra money in the summer, you water your neighbor's lawn and walk their dog. You water their lawn every 6 days and walk the dog every 4 days. Your neighbor pays you $5 each time you walk the dog and $6 each time you water the lawn.When you do both jobs on the same day. she gives you an exrta $3. On june 1, you dont have ro complete either job, because your neighbor did them both the day before. if you worked for your neighbor from june 1 to july 20 ( there 30 days in june and 31 days in july ), how many times would you do both jobs on the same day ? how much total money would earn?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Watering lawn (L) = $6
Walking a dog (D) = $5
Watering lawn and walking a dog = $(6+5+3) = $14
Lawn is watered every 6 days
Dog is walked every 4 days
Working between June 1 to July 31st:
Last time neighbor did both chores = may 30
how many times would you do both jobs on the same day?
Both jobs were done 4 times on the same day between June 1 to July 30
How much in total would you earn from your neighbor from june 1 to July 20th?
Dog walk = (8 * $5) = $40
Watering lawn = (4 * $6) = $24
Both chores = (4 * $14) = $56
$(40 + 24 + 56) = $120
