Correct option is B)
Cross-multiplication is helpful in Solving proportions.
<h3>What is Solving Proportions?</h3>
Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying and solving the resulting equation.
<h3>What are the 2 methods for solving proportions?</h3>
Method I: Draw a double-sided number line, label the parts, set up a proportion and solve.
Method II: Using any method, calculate unit rate and then calculate how many pounds you can get for $30. Method III: Graph a point to represent the original ratio.
<h3>
What is the rule for solving proportions?</h3>

I understand the the question you are looking for is :
Cross-multiplication is helpful in:
a. quadratic equations
b. solving proportions
c. linear equations
d. word problems
please select the best answer from the choices provided a b c d
Answer:
Step-by-step explanation:
Options a and d are right.
The given function is of the above form
We have here a=1/4 :b=1 : p = -pi/3: and k=-1
Hence we have an amplitude of 1/4, horizontal shift of pi/3 to the right,vertical shift of 1 unit down and vertical shrink of 1/4
Hence the correct choices would be
1) It has amplitude 1/4
d) Horizontal shift of pi/3 to the left
Other options are false
You can say:
(241/100 × 10^3) + (358/100 × 10^4) ⇒(241/10^2×10^3)+(358/10^2 ×10^4) ⇒ (241 × 10) + (358 × 10^2) ⇒ 2410 + 35800= 38210 :))
i hope this is helpful
have a nice day
C because 8x8 is 64 and square root of 64 is 8
Answer:
Step-by-step explanation:
No. of blue n(B) = 5
No. of red n(R) = 3
Total marble is N = 8
P(R) = n(R)/N
= 3/8
