11 = -d + 15
PLEASE ANSWER FAST
Answer:
d=4Step-by-step explanation:
Let's solve your equation step-by-step.
11=−d+15
Step 1: Flip the equation.
−d+15=11
Step 2: Subtract 15 from both sides.
−d+15−15=11−15
−d=−4
Step 3: Divide both sides by -1.
−d/−1=−4/−1
Answer:
D= 4
Step-by-step explanation:
11 = -d + 15
-15 -15
-4 = -d
/-1 /-1
D=4
PLZ NEED HELP IMMEDIATELY A jacket usually sells for $61.00. If the jacket is 40% off, and sales tax is 8%, what is the total price of the jacket, including tax?
Answer:
39.53
Step-by-step explanation:
Multiply 61 by .4. The answer is 24.4. Subtract 24.4 from 61. This is the sale price after the discount but before the sales tax. The answer to that is 36.6. Multiply 36.6 by .08, the answer is 2.928. Round to the nearest hundreths. Add this to 36.6. You're final answer is 39.53.

Work out the circumference of this circle.
Take it to be 3.142 and give your answer to 1 decimal place.
9m
Answer:
C = 28.278 m
Step-by-step explanation:
The attached figure shows a circle whose diameter is 9 m.
Radius = Diameter/2
r = 9/2 = 4.5 m
The circumferance of the circle is given by :
C = 2πr
Put r = 4.5 m in the above formula
C = 2 × 3.142 × 4.5
= 28.278 m
So, the circumference of this circle is 28.278 m.

We can write the ratio as 2 : 5
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 is that a group of science students plans to take an SRS of 25 days in the year to see what proportion of days sampled have a low below 0°C in a particular city. Suppose that 41% of days in the city have a low temperature below 0° C.
41% of 25 = (41/100) x 25 = 10.25 = 10 days
So, we can write the ratio as -
10/25
2/5
2 : 5
Therefore, we can write the ratio as 2 : 5.
