How do I do the random guess and test? which it gave me a hint to do so

Problem situation:

stepladder [879]

Answer:

Rewrite so x is on the left side of the inequality.

8 + 4.99x < 20

Move all terms not containing x to the right side of the inequality.

4.99x < 12

Divide each term by 4.99 and simplify.

x < 2.405

The result can be shown in multiple forms.

Inequality Form:

x < 2.405

Interval Notation:

( −∞ , 2.405 )

To make fruit punch, Amar mixes 1 scoop of fruity powder with 5 cups of water. Which recipe ratio will NOT taste the same as Ama

solmaris [256]

Answer:

2 scoops of fruity powder:6 cups of water will not test the same as Amar's recipe

Step-by-step explanation:

Ratios

The proportion or ratios between variables measure the relative quantities of them by doing a division, usually expressed as fractions or a colon-separated pair of numbers.

To make fruit punch, Amar mixes 1 scoop of fruity powder with 5 cups of water. The ratio of fruity powder to water is 1:5.

We must select which recipe from the list won't produce the same ration and therefore will not taste the same as Amar's:

2 scoops of fruity powder:6 cups of water gives a ratio of 2:6. Simplifying by 2, the ratio is 1:3. This recipe will not test the same as Amar's.

2 scoops of fruity powder:10 cups of water gives a ratio of 2:10. Simplifying by 5, the ratio is 1:5. This recipe will test the same as Amar's.

0.5 scoop of fruity powder:2.5 cups of water gives a ratio of 0.5:2.5. Multiplying by 2, the ratio is 1:5. This recipe will test the same as Amar's.

5 scoops of fruity powder:25 cups of water gives a ratio of 5:25. Dividing by 5, the ratio is 1:5. This recipe will test the same as Amar's.

Answer:

2 scoops of fruity powder:6 cups of water will not test the same as Amar's recipe

3(2x+5)=3×+4x how di i solve this step by step

BaLLatris [955]

1. distribute the 3 into the parentheses, so you would now have 6x+15=3x+4
2. combine like terms on the right side , so now you have 6x+15=7x
3. subtract the 6 from the left side so it cancels out and also subtract the 6 from the 7 so now you have 15=x
hope this answers your question !

Quadrilateral ABCD is a parallelogram. DE = 6.1 cm and m∠DAB = 120°. What is BC? cm What is m∠BCD? ° What is AB? cm What is EB?

Ainat [17]

We know that

There are six important properties of parallelograms to know:

1) Opposite sides are congruent (AB = DC and AD=BC).
2) Opposite angles are congruent (D = B and A=C)
3) Consecutive angles are supplementary (A + D = 180° and D+C= 180°).
4) If one angle is right, then all angles are right.
5) The diagonals of a parallelogram bisect each other.
6) Each diagonal of a parallelogram separates it into two congruent triangles.

Part 1) What is BC?
BC=AD-----------> BC=10 cm--------> by Opposite sides are congruent

the answer Part 1) is
BC=10 cm

Part 2) What is m∠BCD?
m∠BCD=m∠DAB-----> m∠BCD=120°----> by Opposite angles are congruent

the answer part 2) is
m∠BCD=120°

part 3) What is AB?
AB=CD------> AB=5 cm----> by Opposite sides are congruent

the answer Part 3) is
AB=5 cm

Part 4) What is EB?
EB=DE-----> EB=6.1 cm----> by The diagonals of a parallelogram bisect each other.

the answer Part 4) is
EB=6.1 cm
