what is the answer to this? −1.2b−5.3≥1.9
Answer:
b≤−6
here u go
Answer:
b ≤ -6 ✅Step-by-step explanation:
To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.
Step 1: Add 5.3We need to reverse the operation - 5.3, so we add 5.3.
-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3
-1.2b ≥ 7.2
Step 2: Divide by -1.2We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.
Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.
-1.2b / -1.2 ≥ 7.2 / -1.2
b ≤ -6 (remember to reverse the sign!)
Step 3: CheckWe now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.
-1.2(-8) - 5.3 ≥ 1.9
9.6 - 5.3 ≥ 1.9
4.3 ≥ 1.9 ✅
We can check again with -6, since this and all numbers smaller than it should be a solution set.
-1.2(-6) - 5.3 ≥ 1.9
7.2 - 5.3 ≥ 1.9
1.9 ≥ 1.9 ✅
b ≤ -6 ✅What does a equal???
Answer:
a=43
Step-by-step explanation:
triangle equals 180.
180-47-90=43
Answer:43
Explanation
PQ=QR
QPR=QRP=47 (angles opposite to equal sides are equal)
PQR= 180-(47+47) = 86
a= 86/2 = 43
2x<6
I need help with this equation
Answer:
-3
Step-by-step explanation: Simplifying
2x + 6 = 0
Reorder the terms:
6 + 2x = 0
Solving
6 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 0 + -6
2x = 0 + -6
Combine like terms: 0 + -6 = -6
2x = -6
Divide each side by '2'.
x = -3
Simplifying
x = -3
Answer:
2x < 6
=> x < 6/2
=> x < 3

Albert bought 9 pounds of fish at a grocery store at $5 per pound for salmon and $3 per pound for catfish. He spent a total of $37 on the salmon and catfish. This can be represented using the following system of equations:5s +3c = 37 s + c = 9 How many pounds of salmon did Albert purchase?
Answer:
5 pounds
Step-by-step explanation:
To find that we simply solve the system of equationsSo make c the subject of the formula of equation 2[tex]s+c=9\\c=9-s[/tex] Substitute in equation 1 [tex]5s+3c=37\\5s+3(9-s)=37\\5s+27-3s=37\\5s-3s+27-(27)=37-(27)\\2s=10\\s=5[/tex] so that's 5 pounds of salmonWhat decimal is equivalent to 5/6?

Answer:

Step-by-step explanation:
I just know please mark brainliest!!!
PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((
Answer: -4
Step-by-step explanation:
Answer:
- 1/4
Step-by-step explanation:
The formula to find slope from two points is (x₂ - x₁) / (y₂ - y₁).
Substituting the points in (2, 4 = x₁, y₁ and 5, -8 = x₂, y₂) we get (5 - 2) / (-8 - 4).
= 3 / -12
= - 1/4
(Tip: when assigning the numbers to the variables, make sure x₁, y₁ are always from the same pair.)

What is the greatest common factor of 60,70, and 80
Answer:
10
Step-by-step explanation:
Answer: The GCF of 60, 70, and 80 is 10.
Step-by-step explanation: If you think about it, the GCF is definitaly going to be 10. That is because you can multiply 10 to get 60, 70, and 80. There is no other number higher than 10 that can be multiplied by something to get all of these values.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given are the questions as mentioned.
Direct variation of {y} with {x} means that as {x} increases, the value of {y} increases uniformly with it. Mathematically -{K} = y/x = constant
Scale factor {K} is a dimensionless value that indicates the constant ratio value indicating direct variation.{ 1 } -
The variables y and x have a proportional relationship.Also y = 15 when x = 3.We can write for proportional relationship as : 15/3 = 4/x{x} = (4 x 3)/15 = 4/5
{x} = 4/5
{ 2 } -
The variables y and x have a proportional relationship.Also y = 9 when x = 2.We can write for proportional relationship as : 9/2 = y/3{y} = (9 x 3)/2 = 27/2 = 13.5
{y} = 13.5
