2(4 + 2x) ≥ 5x + 5? please help

Answers

Answer 1

Answer: 2(4 + 2x) ≥ 5x + 5

First, we will need to expand our problem. Expanding is basically removing the parentheses. To do this, we will look at the first part of the problem to begin with. 2(4 + 2x). Since parentheses usually mean multiplication, we can start with 2(4). So, 2 × 4 = 8. We'll do the same thing with 2(2), 2 × 2 = 4.
$8 + 4x \ge 5x + 5$

Second, our next step is to subtract 4 from each side. We are trying to get the variable (x) on one side of the problem by itself.
$8 \ge 5x + 5 - 4$

Third, we can now simplify (5x) + 5 - (4). I put parentheses around what we are going to focus on. Subtract 5x - 4 to get 1, which can be put as the variable (x). Now we have, x + 5.
$8 \ge x + 5$

Fourth, let's subtract 5 from each side now. This will set up 8 - 5 which equals 3.
$3 \ge x$

Fifth, we can switch sides now to get the result of this problem.
$x \le 3$

Answer: $x \le 3$

5 t-shirts and a hat costs £27.00 2 t-shirts and a hat costs £12.00.
How much does a t-shirt cost?
How much does a hat cost?

Answers

Answer:

£2

Step-by-step explanation:

Let T represent T-shirt and H represent hat

5T + H = £27.00

2T + H = £12.00 Subtract two equation

5T + H - 2T - H = £27 - £12 ➡ 3T = £15 and T = £5 this is the cost for a t-shirt

If a t-shirt costs £5 and 2 t-shirt + a hat costs £12 then a hat costs £2

Let say that t-shirt is X and hat is Y
We get: 5X+Y=27.00
2X+Y=12.00
solve for X in the first equation
5X+Y= 27
5X=27-Y
X=27-Y/5
Replace X= 27-Y/5 in equation 1 or 2
I use equation 2:
2*27-Y/5+Y=12
54-2Y/5+Y=12
make the denominator equal
54-2Y/5+5Y/5=12
54+3Y/5=12
Multiply 5 both side
54+3Y = 60
3Y = 60-54
3Y= 6
Y=6/3
Y=2
Replace Y= 2 in equation 1 or 2
I use 2:
2X+2=12
2X=10
X=5
Thus the answer is T-shirt cost : £5 and hat cost : £2

PLZ HELP ASAP The sides of a quadrilateral are 3, 4, 5, and 6.
Find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.
I've done everything possible and still keep getting wrong answer... plz help

Answers

When a shape's area is 9 times as great, the one dimension difference is √9=3 times as great. Therefore the length of all sides are 3 times of the corresponding sides of the original shape. The shortest side in the original shape is 3, the larger one is 3 times of that, which is 9. General rule, if a similar shape is x times ratio in terms of sides, the area will be x^2 times the original. Hope it helps.
